Summary: Magnesium and its alloys are attractive materials in automotive and aerospace fields due to their low density and high strength. Powder metallurgy technology can reduce deformation and processing of magnesium alloys during preparation process. A high-performance AZ31 magnesium alloy was prepared via vacuum hot-press sintering, and the effects of sintering temperature on the alloy's structure and mechanical properties were investigated. The results showed that at an optimal sintering temperature, the alloy exhibited high strength and favorable elongation due to pressure applied during the sintering process.

Summary: Fe/FeAl2O4 cermet was prepared using a hot press sintering method, forming a new ceramic phase FeAl2O4 during the process. The microstructure and mechanical properties showed an initial improvement followed by deterioration as the Fe mass ratio increased, with the best performance observed at a ratio of 6:1:2. Increasing the Fe mass ratio enhanced Fe and FeAl2O4 wettability, leading to improved diffusion rate and structural influence on FeAl2O4.

Summary: Boron nitride-barium aluminosilicate (BN-BAS) composite ceramics were fabricated by the sol-gel method and hot-pressed sintering. The introduction method of BAS and sintering temperature had significant effects on the phase assemblage, density, mechanical properties and microstructures of the h-BN composite ceramics. The BN-BAS composites prepared by sol-gel method and hot-pressing and sintering exhibited higher mechanical properties compared to the ones prepared by mixing BAS gel powder with h-BN.

Summary: This study investigated the effects of ultrasonic power and time of ultrasonic vibration on the sintered density and ultimate compressive strength of Mg15Nb3Zn1Ca fabricated using ultrasonic-assisted conventional sintering. Increasing ultrasonic power led to higher sintered density and UCS, while prolonged ultrasonic vibration time resulted in decreased performance. The composite material exhibited mechanical properties comparable to cortical bone and improved corrosion resistance when fabricated with specific ultrasonic parameters.
