Simultaneously enhancing the strength and plasticity of Ti-based bulk metallic glass composites via microalloying with Ta
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.
