Room and high temperature dry sliding wear behavior of Boron modified as-cast Ti-6Al-4V alloys against hardened steel

Trace additions of elemental Boron to Ti-6A-4V melt has a marked influence on the as-cast microstructure and mechanical properties. In this study, dry sliding wear behavior of as-cast Ti-6Al-4V alloys containing 0%, 0.3% and 0.55% B was investigated in the temperature range of 300–573 K against the hardened steel as the counterface material. The results indicate that wear rate decreases initially with small additions of B and then increases...
