摘要: 

采用包套热等静压工艺制备了洁净Ti55粉末合金。根据Ti55预合金粉末的β转变温度选择了两个热等静压成型温度, 分析了Ti55粉末合金对热等静压温度和后续的热处理制度的响应。结果表明: 在940℃和970℃热等静压成型的粉末合金, 其显微组织和拉伸性能的差别不大。考虑到在构件热等静压成型过程中存在温度/压力场分布不均匀引起的致密化波动效应, 本文优选的热等静压温度为940℃。固溶时效热处理使粉末合金600℃的拉伸性能显著提高, 其拉伸性能优于铸造合金, 接近锻造合金的水平。有限元模拟仿真可辅助包套/模具设计, 提高效率, 是粉末冶金近净成型构件制备的有效计算仿真工具。应用有限元仿真辅助包套模具设计, 采用热等静压工艺成型了Ti55粉末冶金薄壁筒体结构。

Abstract：

Pre-alloyed powders of T55 have been hot-isostatic-pressed (HIPed) at different HIPing temperatures, and the powder compacts were solution- and aging- treated. Thereafter the powder compacts were carefully examined to establish the relationship between their microstructure and mechanical property. Powder compacts HIPed at 940℃ and 970℃ showed no significant difference on the microstructure and tensile properties. Due to the densification wave effect caused by a non-uniformity of temperature/pressure field during HIPing, the recommended HIPing temperature is 940℃ in this work. The tensile property of powder compact at 600℃ was improved obviously after solution- and aging- treatment. The tensile property of the heat-treated powder compact is close to that of the wrought alloy but better than those of the cast ones. Finite element analysis was used to predict the final dimensions of the small casing component after HIPing, which is well consonant with the experimental data, thus, the FEM analysis is an efficient method for the design and manufacture of powder components. Based on the optimal container design and FEM analysis, a large thin-wall cylindrical structure of Ti55 alloys was manufactured successfully.
Key words： metallic materials    powder metallurgy    hot isostatic pressing    Ti55 alloy    large thin-wall cylindrical structure    finite element analysis
