摘要：

The effects of Ni concentrations and carbon to oxygen (C/O) ratios on the phase formation during the commercial production process and morphology of nonmetallic inclusions were investigated in Ni-rich Ti-Ni alloys. In the process from casting to forging, a phase change from Ti(C,O) to Ti4Ni2OX occurred depending on the Ni concentration and C/O ratios. The phase change from Ti(C,O) to Ti4Ni2OX was easy to proceed in the alloys with low Ni concentrations and C/O ratios, whereas the Ti(C, O) was stable in the alloys with high Ni concentrations and C/O ratios.
