摘要：

In-situ micro-level martensite CuZr phase reinforced Zr50.5Cu27.45Ni13.05Al9 metallic glass matrix composite was synthesized by copper mold casting. Microstructure and compressive properties of the composite are investigated. The martensite CuZr phase possesses numerous coherent twin boundaries, and holds strong interfacial cohesion with the matrix. They both effectively induce the seeding and branching of shear bands during compression. The compressive properties of the composite are therefore improved. The fracture strength and plastic strain of composite with a diameter of 3 mm is up to 2190 MPa, 5.7% respectively. [doi:10.2320/matertrans.M2010031]
