| Abstract: | TA7 ELI titanium rods was used as raw material,and high quality cryogenic titanium alloy spherical powder was fabricated by plasma rotating electrode processes.Then cryogenic titanium alloy material was manufactured by hot isostatic pressing technology,and the microstructure and mechanical properties of the samples were researched.The titanium alloy spherical powder produced by PREP has very well sphericity,high tap-density,narrow granularity distribution,and very low nonmetallic impurity.The PM cryogenic Ti alloy material manufactured by HIP has reached full dense level,the microstructure was fine and isotropy,and the mechanical properties was as well as level of forged material. |
