Synthesis and compressive fracture behavior of a CuZr-based bulk amorphous alloy with Ti additionCHEN Ding(陈鼎), DONG Jian-feng(董建峰), MA Guo-zhi(马国芝)(College of Materials Science and Engineering... measured by compression tests. The structure and thermal characteristics were analyzed by XRD and DSC, and the fracture surface morphology was examined by SEM. The glassy alloy with 4 mm in diameter......
the fracture. Fig.2 Stress-strain curves of alloys A, B, C and D post-quench aged and as-quenched state The case of alloy B does not show the typical stress-strain curve, except the so-called 3-steps feature.... The grain size of thermo-mechanically treated alloys is barely affected by cold working. The fracture strength and ductility increase significantly with the increase of misch metal content when tensile test......
