Abstract:
Liquid-solid compound casting was used to produce two types of AZ91/AlSi12 joints. The magnesium alloy was the cast material poured onto a solid aluminium alloy insert with an unmodified or modified structure. The bonding zone obtained for the unmodified insert was not uniform in thickness. There was a eutectic region (Mg17Al12 + a solid solution of Al in Mg) in the area closest to the AZ91. The region adjacent to the AlSi12 had a non-uniform structure with partly reacted Si particles surrounded by the Mg2Si phase and agglomerates of Mg2Si particles unevenly distributed in the Mg-Al intermetallic phases matrix. Cracks were detected in this region. In the AZ91/AlSi12 joint produced with a thermally modified AlSi12 insert, the bonding zone was uniform in thickness. The region closest to the AZ91 alloy also had a eutectic structure. However, significant microstructural changes were reported in the region adjacent to the modified AlSi12 alloy. The microstructure of the region was uniform with no cracks; the fine Mg2Si particles were evenly distributed over the Mg-Al intermetallic phase matrix. The study revealed that in both cases the microhardness of the bonding zone was several times higher than those of the individual alloys; however, during indenter loading, the bonding zone fabricated from modified AlSi12 alloy was less prone to cracking.

Abstract:
Abstract The effect of Sr addition on the microstructure and time-dependent corrosion properties of the AlSi12 eutectic alloy was investigated. The modified alloy contained 90 ± 3 ppm Sr. The microstructural differences in the eutectic structure of AlSi12 alloys were assessed in terms of the Si particle size and a-Al volume fraction. The unmodified and Sr-modified alloys were immersed for 1, 24, 72 and 120 h in 3.5 wt.% NaCl. Electrochemical impedance spectroscopy and potentiodynamic polarization techniques were performed to analyze the corrosion characteristics of the alloys. Sr addition led to a decrease in the Si particle size, and the formation of long dendritic a-Al. It was found that the presence of Sr resulted in more stable corrosion behavior up to 24 h. The deterioration of the corrosion behavior of Sr-modified alloy was observed with the further increase of immersion time.

Abstract:
Purpose: Determine the possibility of modifying aluminium alloys of the Al-Si system with an ultrafine SiC modifier with a particle size of 3-5 μm. Design/methodology/approach: Processing of the Al-Si alloy was carried out by introducing an ultrafine modifier in the amount of 0.1, 0.2, or 0.3 wt.%. Silicon carbide (SiC) with a particle size in the range of 3-5 μm was used as a modifier. To study the microstructure of the formed surface layers, a metallographic analysis was performed according to the standard method on a microscope MIKPOTEX® MMT-14C using TopView software. Microhardness studies of the samples were carried out on a Vickers microhardness tester NOVOTEST TC-MKV1. The microstructure of castings of the AlSi12 grade was studied at magnification from 100 to 400 times on the horizontal and vertical surfaces of the samples after etching with a 2% NaOH aqueous solution. Findings: Aluminium cast alloy of Al-Si system has been synthesized with the addition of 0.1, 0.2, and 0.3 wt.% ultrafine SiC modifier. It was found that the modification of the AlSi12 alloy by SiC particles of 3-5 μm in size led to an improvement of its microstructure due to the reduction of the volume fraction of micropores and primary Si crystals. It was shown that the AlSi12 aluminium alloy due to the modification by 0.2 wt.% SiC has the best micromechanical properties and macrostructure density. Research limitations/implications: The obtained research results are relevant for cast specimens of the indicated sizes and shapes. The studies did not take into account the influence of the scale factor of the castings. Practical implications: The developed modification technology was recommended for use in the conditions of the foundry "Dnipropetrovsk Aggregate Plant" (Dnipro, Ukraine). Originality/value: The technology of AlSi12 alloy modification of ultrafine SIC modifier with a particle size of 3-5 μm was used for the first time.

Abstract:
Additive manufacturing (AM) technologies make it possible to produce complex shape metallic objects from powder feedstock. AlSi12 alloy is one of the most widely used materials in selective laser melting (SLM). The large number of technological parameters involved complicate the selection of an SLM mode for obtaining a product with the required structure. The goal of this research was to determine the mode which ensures the material’s low porosity. Nine specimens were fabricated by using different SLM process parameters. The fabricated specimens have different microstructures. The lowest porosity that was achieved is about 0.5%.

Abstract:
A new coating based on polymer-derived ceramics (PDC), oxides and refractory ceramic with a thickness of around 50 µm has been developed to improve the resistance corrosion of stainless steel substrate against molten aluminum alloy in a thermal energy storage (TES) system designed to run at high temperature (up to 600 °C). These coatings implemented by straightforward methods, like tape casting or paintbrush, were coated on planar and cylindrical stainless-steel substrates, pyrolyzed at 700 °C before being plunged for 600 and 1200 h in molten AlSi12 at 700 °C. The stainless-steel substrate appears healthy without intermetallic compounds, characteristic of molten aluminum alloy corrosion. The protective coating against AlSi12 corrosion shows excellent performance and appears interesting for TES applications.

Abstract:
Particle-reinforced MMCs (pMMC) such as aluminum alloys reinforced with ceramic silicon carbide particles (AlSiC) require special cutting tools due to the high hardness and abrasive properties of the ceramic particles. Diamond coated cutting tools are ideal for machining this type of pMMC. Previous research studies focus on the machinability of pMMCs with low ceramic content. The aim of this research is to determine the optimal cutting parameters for machining AlSiC material containing high silicon carbide particle reinforcement (>25%). The optimal cutting parameters are determined by investigating the relationship between cutting forces, tool wear, burr formation, surface roughness, and material removal rate (MRR). Experimental milling tests are conducted using CVD diamond coated end mills and non-diamond tungsten carbide end mills. It was found that low tool rotation speeds, feed rates and depths of cut are necessary to achieve smoother surface finishes of R a < 1 μm. A high MRR to low tool wear and surface roughness ratio was obtainable at a tool rotation speed of 6500 r/min, feed rate of 762 mm/min and depth of cut of 3 mm. Results showed that a smooth surface roughness of the workpiece material was achieved with non-diamond tungsten carbide end mills, however, this was at the expense of extreme tool wear and high burr formation. The use of coolant caused a 50% increase in tool wear compared to the dry-cutting experiments which had lower cutting tool forces.

Abstract:
Concentrating solar power (CSP) plants with thermal energy storage offer several advantages to plants without storage. Thermal energy storage (TES) allows CSP plants to produce power for longer periods of time each day, making them produce energy more like traditional, fossil fuel power plants. TES also gives the ability to time shift production of energy to times of peak demand, allowing the plant to sell the energy when prices are highest. A CSP plant with storage can increase turbine performance and reach higher levels of efficiency by load leveling production and can remain productive through cloud transients. Power tower CSP plants are capable of producing extremely high temperatures, as they have the ability to oversize their solar field and achieve a greater concentration ratio. Studies have been conducted on variable working fluids, leading to higher working temperatures. This theoretically allows power towers to use more efficient, higher temperature cycles including the recuperated air Brayton cycle, although none currently exist on a commercial scale. This research focuses on developing a model of a high temperature TES system for use with an air Brayton cycle for a power tower CSP plant. In this research we model one module of a latent heat TES system designed to meet the thermal needs of a recuperated Brayton engine of 4.6 MWe capacity for six hours. A metal alloy, aluminum-silicide (AlSi), is considered as the phase change medium. The storage tank is approximately 161 m3, or a cylinder with a 5 m diameter that is 8 m tall filled with AlSi with several air pipes throughout the volume. We model the volume around a single pipe in a 2-D cylindrical coordinate system, for a module size of 0.2 m in diameter and 8 m long. The advantages of using AlSi alloys is that they have variable melting temperatures depending on the relative concentration of the two metals, from 577 C for the eutectic composition of 12.6% silicon to 1411 C for 100% silicon. This attribute is taken advantage of by the TES model as the composition of the AlSi alloy will vary axially. This will allow a cascaded type storage system within one tank and with one material. The use of FLUENT to model this problem is first validated by several analytical solutions including Neumann’s exact solution for a one-dimensional Cartesian geometry and the Quasi-Steady Approximation in a 1-D cylindrical geometry. The model developed will establish charge/discharge times for the storage system, round-trip efficiency of the system, ability of the system to meet the demand of the Brayton cycle, and the validity of using off-eutectic metal alloys in a cascade as a latent heat TES medium.

Abstract:
Abstract Experimental devices in a deteriorated state were encountered after 168 hours of inductive operating life stress, (IOL) testing. A metal grain boundary breakdown mechanism was found during the analysis of the device, which was creating a low resistance current path between terminals. The AlSiCu top metal was breaking down along the grain boundaries. In addition there was alloying of the Aluminum into the underlying silicon. This alloying was creating a short to the gate, source, and drain. Several variations in the metal stack, testing conditions, number, and dimensions of bond wires die size and mold compound were evaluated to better understand the cause of the inability to withstand IOL stress and to provide a process solution. The prevention of the AlSiCu front metal grain boundary breakdown during inductive life stress testing required a die size, bond wire dimension, and testing condition change to meet the performance specification. This change resulted in a reduced grain boundary breakdown and consequently prevented Al grain boundary breakdown, TiW barrier breakdown, and Al alloy spiking. The die change and modified testing conditions resulted in a successful pass through the IOL stress testing.

Abstract:
Concentrated solar power (CSP) must decrease its levelized cost of electricity (LCOE) below the DOE SunShot program targets of 6 ¢/kWhe and improve its reliability to enable widespread adoption. Two features of CSP that will decrease LCOE and improve reliability are higher operating temperatures for the power cycle and thermal energy storage (TES). Thermaphase Energy and San Diego State University are developing the Liquid Metal Thermal Energy Storage System (LiMTESS), an innovative TES system based on phase change in Al-Si and Mg-Si alloys that stores thermal energy produced by gas-cooled solar receivers at temperatures above 800 C. Proper containment for Al-Si and Mg-Si alloys is critical for LiMTESS commercialization. Any containment vessel must be simultaneously compatible with the molten alloys and high-temperature oxidizing gases (e.g., air), facilitate heat transfer between the alloys and high-temperature oxidizing gases, and accommodate internal stresses associated with TES operation. A ceramic-metallic composite material (TCON) and select ceramics such as siliconized silicon carbide (SiSiC) and alumina initially showed promise in meeting these requirements. A series of thermal cycling tests were performed to check the integrity of the containment vessels. TCON produced macroscopic nodules during the thermal cycling that eliminated it from further consideration. On the other hand, SiSiC performed well when exposed to high-temperature, AlSi36, MgSi56, and air. To further evaluate SiSiC as a containment material, the research team conducted multiple thermal cycles with variable temperature profiles, duration of test, and gas environments. Before and after each thermal cycle, the team conducted a mass analysis and performed SEM and EDS analysis on prepared, treated samples. The results confirm SiSiC is a good candidate for a containment vessel. At this point the research team is evaluating Morcoset, a silicon carbide-based mortar, for creating an air-tight seal for SiSiC. The research team assessed the quality of the seal by using the mortar to seal MgSi56 and conducted thermal cycling tests to compare the mass loss of the system due to Mg vapor escaping the system to that of a controlled system with no alloys sealed. Results confirmed that Mg vapor did not exit the system. There is still more work to do, but preliminary results indicate the Morcoset + SiSiC system is a good containment system for AlSi36/MgSi56. In this paper the results of the long-duration thermal cycling tests as well as electron micrographs of the containment seals and phase change materials are presented.
