content. Key words: powder compaction; high strain rate; Mg-B4C composite; hardness; mechanical properties; wear behavior 1 Introduction Nowadays, the modern world is moving towards a new era in which..., the average friction coefficient is reduced from 0.32 to 0.29 for Mg–5.0%B4C. In general, the reduction of friction coefficient is considered due to the high hardness of reinforcement and the low......
