Abstract

We report the formation of nanocrystals in the shear band of a Ti₄₀Zr₂₉Cu₉Ni₈Be₁₄ bulk metallic glass which exhibits a large plastic strain. The nanocrystals in the shear band have the same crystal structure as the high temperature Laves phase which appears during crystallization by heating, strongly suggesting a temperature rise in the shear band.
