  • Microstructures and mechanical properties of B4C-TiB2-SiC

    After 12 h ball milling treatment, the particle size of the powder mixture decreased from 2.06 μm to 1.21 μm, when the ball milling time increased to 24 h, the particle size only decreased from 1.21 μm to 0.96 μm. It is evident that the ball milling effect was significant before 12 h, and became weaker between 12 and 24 h. This could be attributed to the fact that, when the milling time
