Abstract

We produced large size Ni-free Ti-based bulk metallic glasses (BMGs) by a spark plasma sintering (SPS) process using gas-atomized Ti ₄₅Zr ₁₀Cu ₃₁Pd ₁₀Sn ₄ glassy alloy powders. The effects of sintering temperature on densification, structure, mechanical properties and corrosion behavior in Hanks' solution of the sintered samples were investigated. The high strength sintered samples with high densification and no crystallization were obtained by the SPS process at a sintering temperature of 643 K with a loading pressure of 600 MPa. The BMGs produced by the SPS process can offer excellent properties and satisfying large sample-size requirements. The Ti-based BMGs without toxic elements open possibilities of application as biomedical materials.
