Abstract
Due to high strength, perfect plasticity and higher hardness, bulk metallic glass (BMG) has been widely concerned. The work used the vaccum casting of copper-formed mold to establish (Ti36.1Zr33.2Ni5.8Be24.9)100-xCux,
where x = 3, 5, 7, 9 and 11. Thermal properties, mechanical behaviors of compression, and corrosion resistance in the proposed compounds were investigated. The results show that the increase in Cu content enhances the heat resistance and the forming of glass of BMGs, small amount of
fine dendritic crystals presents in BMG when x = 3, and the best corrosion resistance and mechanical properties can be obtained when x = 7, the yield strength, fracture strength and plastic strain can reach 1496.15 MPa, 2003.44 MPa and 19.19%, respectively.
