摘　　要：本文通过探讨激光选区熔化的成形原理及应用现状,从TC4成形工艺、成形组织、力学性能、质量等级等方面,将激光选区熔化TC4制件与传统锻铸件间的区别进行了简单分析。结果表明,相较于传统锻件、铸件而言,激光选区熔化制件材料利用率更高,制造周期更短;静态力学性能高于钛合金铸件性能,达到甚至超过锻件性能;激光选区熔化制件质量级别处于中等,比锻件质量级别低,但高于铸件质量级别。By discussing the forming principle and application status of laser selective melting,the difference between laser selective melting TC4 parts and traditional forging castings is briefly analyzed from the aspects of TC4 forming process,forming structure,mechanical properties and quality grade.The results show that,compared with traditional forgings and castings,the material utilization rate of laser selective melting parts is higher and the manufacturing cycle is shorter;the static mechanical properties are higher than the performance of titanium alloy castings,reaching or even exceeding the performance of forging parts;laser selective melting parts The quality level is medium,lower than the forging quality level,but higher than the casting quality level.
