Abstract (sommario):

Transition metal carbide nanoparticles are a class of technological interesting materials with a wide range of applications. Among metal carbides, tantalum carbides have good compatibility with the biological environment while molybdenum carbides are used as catalyst in electrochemical reactions. Laser ablation of bulk transition metal targets in some liquids is here reported and laser ablation in organic solvents is used as simple synthetic strategy for the production of carbide nanostructures. Herein, the nanoparticles produced by ultra-short laser ablation of tantalum and molybdenum in wate

Abstract (sommario):

The characteristics of primary carbides in a commercial-sized (one ton) electroslag remelting (ESR) ingot of AISI H13 steel were investigated. The interaction between the primary carbides and inclusions was also clarified. The results indicate that there are two types of primary carbides, V-rich and Mo-rich primary carbides, in the H13 ESR ingot. The quantity, the area fraction, and the size of the two primary carbides tend to decrease from the center of the H13 ESR ingot to the outer surface. Additionally, the V-rich primary carbide is obviously larger than the Mo-rich primary carbide. The Al

Abstract (sommario):

The Ti element plays a role in pinning grain boundaries but also has a good binding ability to C and N, forming large primary carbides. Therefore, the effect of Ti content on primary carbides’ behavior in H13 ingots was comprehensively studied. A non-aqueous electrolysis method was used to determine the three-dimensional (3D) characteristics of primary carbides. We found a great difference between the two-dimensional (2D) and the three-dimensional characteristics of primary carbides. When performing 2D analyses, the density of the primary carbides appeared high, while their size was small. The

Abstract (sommario):

Background: Ductile irons provide a more viable alternative for malleable cast iron in areas that do not demand extreme wear resistance. Austempering of ductile irons was a well researched area in the last two decades. Attempts to further improve the wear resistance led to the development of Carbidic austempered ductile iron (CADI), wherein the carbides contribute to wear resistance. Combination of ausferritic matrix, graphite nodules, and carbides (eutectic and alloy) symbolizes the microstructure of CADI. Methods: Two principal approaches adopted by the researchers to change the microstructu

Abstract (sommario):

In this study, mechanical degradations in 2.25Cr-1Mo steel were evaluated by quantitative morphological analysis of carbides. Based on the morphology, carbides were classified as globular, fine acicular, rod, and grain boundary one. Mean size of carbides were determined as a function of morphology and thermal degradation time at 630°C. Area fraction of grain boundary carbides and fraction of grain boundary M6C carbides were observed to increase rapidly in the initial stage of degradation and then gradually afterwards. Both mean size of globular carbide and fraction of grain boundary M6C carbid

Abstract This article presents the results of investigations of the effect of heat treatment temperature on the content of the carbide phase of HS3-1-2 and HS6-5-2 low-alloy high-speed steel. Analysis of the phase composition of carbides is carried out using the diffraction method. It is determined that with increasing austenitising temperature, the intensification of dissolution of M6C carbide increases. As a result, an increase in the grain size of the austenite and the amount of retained austenite causes a significant reduction in the hardness of hardened steel HS3-1-2 to be observed. The r

AbstractThe vulnerability of tempered martensitic steel to hydrogen embrittlement (HE) has attracted attention from a number of researchers. Although utilizing carbide precipitation is one of effective methods to improve HE resistance, few studies have focused on the effects of carbide characteristics, such as the chemical composition and morphology of carbide. This work clarifies the role of Mo carbide and V carbide in the HE behavior of tempered martensitic steels with four steels whose chemical composition was carefully controlled.

The effect of Mg on carbides precipitation in H13 steel was studied based on the Thermo-Calc thermodynamic calculation.

The as-cast microstructure and the characteristic of carbides in Mg-containing H13 steel were analyzed by OM and SEM-EDS. The results showed that the segregation of as-cast microstructure was released and the size of carbides was reduced by increasing Mg. The distribution of carbides was more homogeneous

Abstract (sommario):

Carbide precipitation in martensitic low alloyed steels contributes to the mechanical properties through precipitation hardening. A high number density of carbides is desired to maximize the hardening effect, which is achieved through the precipitation of carbides on the dislocations in the martensitic structure. In this study, the nucleation, growth, and coarsening of vanadium and molybdenum carbides during aging at 600 °C for periods up to four weeks were investigated. The work covers characterization with atom probe tomography, which showed that the nucleation of V and Mo rich MC/M2C carbid

High temperature environmental scanning electron microscopy (HT-ESEM) was used to examine in situ the oxidation of both ZrC and UC.

It is believed that carbide particles can act as hydrogen trapping sites, thus reducing the risk of embrittlement.

Abstract High-alloy steels, like Ferrium C64, are used in powertrain components due to their corrosion resistance and high temperature resistance properties.

In the early stages of tempering, softening occurs due to the formation and coarsening of iron carbide, followed by a hardening as the alloy elements combine to form nano-scale dispersoids.

Abstract (sommario):

Abstract Furnace tubes are essential parts in the petroleum refining processes, and it is important to know how to use them safely. This study investigates the microstructures and properties of HP furnace tubes at elevated temperature. As the treating temperature increases, the secondary carbides precipitate around the eutectic carbides initially and in austenitic matrix progressively. Above 900 °C, the secondary carbides redissolve in the matrix, and needle pattern carbides renucleate and grow. The hardness and polarization curve of different heat treated HP tubes are also measured to reveal

Abstract (sommario):

Abstract Synergistic erosion and corrosion at elevated temperatures is a prevalent condition in oil refining and power generation. Corrosion resistant alloys do not tend to be durable under wear conditions, whilst common wear-resistant solutions such as tungsten carbide-based coatings display poor resistance to oxidation and corrosion. This work details the development of a composite overlay, deposited by plasma transferred arc welding, that has been designed to exhibit high levels of wear protection coupled with resistance to oxidizing and carburizing environments. The performance of the comp
