Abstract
Zr50Cu40Al10 bulk metallic glass (BMG) matrix composite with crystalline B2 ZrCu was fabricated. Compressive test was carried out using the composite specimens with different volume fraction of B2 ZrCu. The effects of B2 ZrCu on plastic deformation behavior and mechanical properties of the composite were investigated. As the results, it was found that the ductility of the composite specimen was enhanced by increasing of volume fraction of B2 ZrCu. Also, it was found that the composite specimen exhibited work hardening behavior. On the other hand, yield stress and Young's modulus of the composite decrease with increasing of volume fraction of B2 ZrCu. Furthermore, it was confirmed that a stress-induced martensitic transformation in B2 ZrCu phase occurs during compressive test.
