Abstract
A metastable Ti-based metallic glass matrix composite (MGMC) exhibits deformation behavior that is closely related to the temperature and strain rate in the supercooled liquid region. The state of the amorphous matrix varies with the temperature, resulting in different responses to the overall mechanical properties. The remarkable strain rate sensitivity makes the strength of this MGMC reach 1,355 MPa, which is more than that of most MGMCs at diverse strain rates. In addition, serration deformation induced by martensite transformation is found in MGMC, which is different from serrated flow caused by the movement of shear bands in metallic glasses. The serration behavior changes synchronously with the martensite transformation.
