Summary: Bioactive glasses incorporating metallic ions, such as Cu-45S5, have promising applications in bone tissue engineering due to their antibacterial activity and ability to stimulate osteogenesis and angiogenesis. This study investigated the structural changes of Cu-doped 45S5 BG during sintering, revealing the formation of combeite and rhenanite crystalline phases, as well as the presence of a residual glassy phase enriched with Na and P ions. The crystallinity and crystal size of Cu-45S5 glass-ceramics can be adjusted through appropriate heat treatment, with Cu localized in the residual glassy phase affecting the release of Cu ions in physiological environments.

Summary: The hygroscopicity of coal powder is influenced by factors such as particle size, temperature, and relative humidity. Increasing particle size leads to a decrease in maximum moisture adsorption capacity and an increase in effective moisture adsorption time. Higher relative humidity significantly increases the maximum moisture adsorption capacity of coal powder. Different ranks of coal powders exhibit varying degrees of hygroscopicity, with low-rank coal showing the strongest water absorption ability. This study provides valuable insights for evaluating the moisture status, transportation efficiency, and combustion performance of coal powder.

Summary: The properties of metal matrix composites are influenced by various process variables, and in this study, an aluminum-based MMC with varying proportions of SiC as reinforcement material was fabricated using different mixing techniques. Experimental investigations showed that mixing powders with a barrel mixer led to improved hardness and compressive strength compared to conventional V-blender mixing. Increasing SiC content by 5% resulted in a 14% increase in hardness, and the highest compressive strength was achieved when the reinforcement content was 25%. Furthermore, the uniform dispersion of particles achieved through the barrel mixer led to higher compressive strength and hardness for the MMC compared to those mixed through a conventional V-blender. This novel approach to powder mixing provides an effective solution for fabricating Al-MMC through the powder metallurgy process.

Summary: The influence of sintering temperature, dwelling time at maximum temperature and carbon content on the microstructure and mechanical and magnetic properties of WC-6%Co hardmetal was investigated. Results showed that to maximize hardness and transverse rupture strength (TRS), sintering should be performed at a low temperature (< 1400°C) and with a dwelling time of at least 75 minutes. This is particularly important for low carbon parts to ensure the necessary microstructure homogeneity required for high TRS.

Summary: By regulating the microstructure of TaBx films deposited by magnetron sputtering, the hardness and wear resistance of the films can be improved. With the increase of the bias voltage, the B content decreases and the crystallinity is enhanced. The microstructure of the films transforms from fibrous to dense columnar and then to granular structure. At a bias voltage of -180 V, the films exhibit super high hardness and relatively moderate fracture toughness.

Summary: This study successfully optimized the toughness of polycrystalline diamond (PCD) by adjusting the intergranular fracture (IF) and transgranular fracture (TF) modes. The results showed that a mixture of the IF and TF modes resulted in higher hardness and toughness in PCD compared to a single fracture mode. The toughness of the PCD was approximately three times that of single-crystal diamonds and comparable to that of pure nanotwinned diamonds. The mixed modes introduced toughening mechanisms such as high frequency large crack deflection, crack bridging, pull-out, and crack branching, which increased the toughness of the PCD.

Summary: The particle size and morphology of tungsten powders play a crucial role in determining the processing properties of tungsten products. This study investigated the effects of water vapor partial pressure on the hydrogen reduction of tungsten oxides, and proposed a method of changing the particle size of tungsten powders using bottom blowing hydrogen. The experimental results showed that bottom-blowing hydrogen could improve the uniformity of tungsten powders in a crucible by eliminating discrepancies in water vapor partial pressure. The partial pressure of water vapor increased with the temperature of the water bath, leading to an increase in the average particle size of tungsten powders.
