Influence of Speed and Sliding Distance on the Tribological Performance of Submicron Particulate Reinforced Al-12Si /1.5 Wt% B4C Composite

Deepak M. Shinde et al.

Summary: The study investigates the wear and friction performance of Al-12Si aluminum alloy reinforced with 1.5 wt% submicron boron carbide (B4C) particles. Results show that the dispersion of B4C particles in the aluminum matrix enhances wear resistance of the composite material. The wear mechanism is primarily influenced by adhesion and delamination in the base alloy, while the mechanically mixed layer plays a key role in the wear performance of the composite matrix.

Microstructure and mechanical properties of WMoTaNbTi refractory high-entropy alloys fabricated by selective electron beam melting

Bang Xiao et al.

Summary: WMoTaNbTi RHEAs formed by SEBM with negative defocus distance were studied. The results show that the decrease in scanning speed leads to vaporization of Nb and Ti elements, weakening the solid-solute strengthening and reducing the content of Nb and Ti solutes in the matrix, resulting in improved ductility and decreased microhardness. The as-deposited WMoTaNbTi RHEA formed at a scanning speed of 2.5 m/s exhibits high ultimate strength.

Insight into the formation mechanism and interaction of matrix/TiB whisker textures and their synergistic effect on property anisotropy in titanium matrix composites

Jianwen Le et al.

Summary: Considerable studies have been done on property anisotropy induced by crystallographic textures in processed pure titanium and titanium alloys, but limited information is available for the intrinsic coupling of matrix and reinforcement textures and their synergistic effect on property anisotropy in titanium matrix composites. In this study, an advanced EBSD/EDS coupling method was used to investigate the formation mechanism of primary alpha and secondary alpha textures in the matrix alloy. It is revealed that the reinforcement TiBw displays a specific texture after hot rolling and has little effect on the matrix texture component. Significant anisotropies in the tensile strength and ductility can be observed, which is the synergistic effect of the matrix texture and the aligned TiBw.

Tomas Vlasak et al.

Summary: In this study, a series of high-entropy alloys based on refractory metals were systematically investigated. It was found that a bcc single-phase solid solution can be formed at high temperatures, but phase separation occurs at lower temperatures. However, a metastable single-phase solid solution can be preserved at room temperature through rapid cooling. Moreover, the mechanical properties of annealed and as-cast alloys were found to be comparable.

Formation of MoSi2 and Si/MoSi2 coatings on TZM (Mo-0.5Ti-0.1Zr-0.02C) alloy by hot dip silicon-plating method

Yingyi Zhang et al.

Summary: MoSi2 and Si-MoSi2 composite coatings with fine MoSi2 grain size and high surface silicon concentration were successfully deposited on TZM alloy using a hot dip silicon-plating method. The gradient structure of the coatings, including MoSi2 layer, Mo5Si3C layer, and Si-MoSi2 layer, contributes to reducing stress mutation and crack propagation. SEM and CLSM results demonstrate that a significant portion of MoSi2 grains are covered by silicon layer, leading to very low coating surface roughness when deposition time exceeds 10 minutes.
