Abstract
Zr-Cu-Al bulk metallic glass matrix composite with crystalline B2 ZrCu was fabricated. Compressive test was carried out using the composite specimens with high volume fraction of B2 ZrCu in order to investigate the mechanical properties and deformation behavior of B2 ZrCu. As the results, it was found that the mechanical properties of the composite depend on the volume fraction of B2 ZrCu. Compressive strength, yield stress and Yong's modulus of the composite decrease with increase of volume fraction. On the other hand, plastic strain increases with increase of volume fraction. In addition, it was confirmed that a stress-induced martensitic transformation in B2 ZrCu occurs during compressive test. Furthermore, it was confirmed that the composite with high volume fraction of B2 ZrCu exhibits shape memory effect.
