摘要

Abstract

BSTRACTCharacteristics of deformation-induced transformation under loading dictate the mechanical performance of TRIP (transformation-induced plasticity)-reinforced bulk metallic glass composites (BMGCs)

which have shown great potential as engineering materials. Here

we report that the addition of 0.3 at.% Ta in the Ti45Cu41Ni9Zr5 alloy could induce the formation of uniform glassy composite structure with B2-(Ti

Zr)(Ni

Cu) precipitates. More interestingly

nanosized A2-(Ti

Zr)(Ni

Cu) particles also formed inside B2 grains which effectively impede rapid propagation of martensite plates and lead to the formation of multi-oriented martensites

eventually homogenizing the involved plastic flow during deformation-induced transformation. Consequently

high fracture strength (∼3000 MPa)

large plasticity (∼25%) and pronounced work-hardening ability were achieved.
