Abstract

To achieve plasticity of Ti-based bulk metallic glasses (BMGs) without sacrificing their high strength, the microstructure of Ti50Cu20Ni24Sn3Si2B1 alloy was tailored to form in situ composites. The cast rods consist of micrometer-sized NiTi dendrites surrounded by a thin metallic glass network along with a fine CuTi3 phase. The rods show high strengths of 19002250 MPa and plastic strains of 4.57.8%, which are superior to the monolithic Ti-based BMGs. The microstructureproperty correlations and the deformation behavior are investigated.
