Abstract (sommario):

Abstract Porosity is one of the major defects in aluminum castings, which results is a decrease of a mechanical properties. Porosity in aluminum alloys is caused by solidification shrinkage and gas segregation. The final amount of porosity in aluminium castings is mostly influenced by several factors, as amount of hydrogen in molten aluminium alloy, cooling rate, melt temperature, mold material, or solidification interval. This article deals with effect of chemical composition on porosity in Al-Si aluminum alloys. For experiment was used Pure aluminum and four alloys: AlSi6Cu4, AlSi7Mg0, 3, Al

Abstract (sommario):

Most traditional aluminium casting alloys are based on the aluminium-silicon eutectic system because of its excellent casting characteristics. However, the solidus in this system does not exceed 577 °C and the major alloying elements used with silicon in these alloys have high diffusivity in aluminium. Therefore, while these elements enhance the room temperature strength of the alloy, they are not useful at elevated temperatures. Considering nickel-base superalloys, whose mechanical properties are retained up to temperatures that approach 75% of their melting point, it is conceivable that cast

Abstract (sommario):

The AlCrFeCoNi high entropy alloy exhibits unexpected properties that can be obtained after mixing five different elements, which could not be obtained from any one independent element. The difference to conventional alloys is that these alloys may have, at the same time, both hardness and plasticity, can be used in severe impact applications. In order to study the influence of aluminum content on the microhardness and microstructure of the high entropy alloys AlxCrFeCoNi (x: atomic ratio, x= 0.2 to 2.0) nine types of samples were obtained as mini-sized ingots (50x15x9.5 mm and 40 g weight).

Abstract (sommario):

Aluminium matrix composite is a type of innovative technical material that have applications in aerospace, automotive, biotechnology, electronics, and a lot more. Non-metallic reinforcements can be injected into an aluminium alloy to provide advantages over base metal (Al) alloys. Better mechanical properties, improved microstructure, and corrosion resistance are the benefits that have been noticed upon reinforcements. The proportion of reinforcement, kind, size, and forms of aluminium matrix are all important factors in improving mechanical and tribological properties. Investigation in the cr

Abstract The most commonly used aluminum alloys for manufacturing rims are the deformable alloys 6082 and 6061, as well as the casting alloy AlSi11. The increasing demand for such materials has led to intensified research and development activities in the field of high-strength and high-ductility aluminum alloys. Aluminum alloy rims must meet certain critical safety requirements and adhere to high standards of design, technical conditions, and processing. This paper presents the research conducted and the results obtained regarding the load structure in the processing of 6082 aluminum alloys i

Abstract (sommario):

In this article, a creep–rupture model of aluminum alloys is developed using a time-dependent cohesive zone law. For long-term creep rupture, a time jump strategy is used in a cohesive zone law. Stress–rupture scatter of aluminum alloy 4032-T6 is fitted with a power law form. Then, change in the slope of a stress-rupture line is identified on a log–log scale. Implicit finite element analysis is employed with a model containing a cohesive zone. Stress–rupture curves at various given temperatures are calculated and compared with experimental ones. Results show that a proposed method allows predi

Abstract (sommario):

Pre-precipitate (cluster) strengthening is an integral aspect in the design of novel aluminum alloys. To investigate the impact of clusters on the strength of different aluminum alloys, Monte Carlo methods and the modified embedded atom method potential function were employed to simulate dilute aluminum-rich solid solutions, and these ten elements (silicon, magnesium, manganese, titanium, zirconium, chromium, iron, lithium, copper and nickel) were added as solute elements. The yield strength was evaluated and then the relationships among cluster size, cluster number, yield strength, and alloy

Abstract (sommario):

Currently liners of high-pressure hydrogen storage container for fuel cell vehicles are manufactured from the 6061 aluminum alloy pipes through spinning at elevated temperatures. Since the surroundings of the containers are reinforced with a large amount of high-cost CFRP, the use of 6066 or 6069 aluminum alloy with higher strength than 6061 is demanded to lower the cost of the container. However, the formability of these aluminum alloys at elevated temperatures has not been elucidated yet. In this study, tensile deformation characteristics of 6066 and 6069 aluminum alloys at temperatures rang

Abstract (sommario):

As one of the lightest structural metals, the application breadth of aluminum alloys is, to some extent, constrained by their relatively low wear resistance and hardness. However, laser cladding technology, with its low dilution rate, compact structure, excellent coating-to-substrate bonding, and environmental advantages, can significantly enhance the surface hardness and wear resistance of aluminum alloys, thus proving to be an effective surface modification strategy. This review focuses on the topic of surface laser cladding materials for aluminum alloys, detailing the application background
