Published in 2017 at "Journal of Alloys and Compounds"

DOI: 10.1016/j.jallcom.2017.04.218

Abstract: Abstract In this paper, in-situ β-Ti phase reinforced (Al, Ni, Be)-free Ti-based bulk metallic glass matrix composites (BMGMCs) were developed by microalloying Mo. The BMGMCs showed higher fracture strength and larger plastic strain than the… read more here.
