Microstructure and mechanical properties of Ti48Zr18V12Cu5Be17 bulk metallic glass composite

Abstract Microstructure and mechanical properties of Ti 48 Zr 18 V 12 Cu 5 Be 17 bulk metallic glass composite were investigated. The research shows that the microstructure mainly consists of amorphous matrix and β-Ti phase. However, the β-Ti phases are inhomogeneous distribution in glass matrix, which relates to composition hardly, but highly dependent to the comprehensive effects of fluid flow, thermal field and free grains. Upon the quasi-static compression, the amorphous composite shows high yield strength about 2016 MPa and a plastic strain about 10.91%. In addition, the deformation mechanisms of the BMGCs were also experimentally and theoretically explored.
