通过单轴压缩实验，对镍基高温合金粉末压坯热等静压有限元分析中使用的Shima屈服准则进行了修正。通过模拟和实验研究了圆柱形胶囊特性对FGH4096M高温合金粉末热等静压成形和致密化行为的影响。结果表明，模拟收缩预测与实验收缩吻合较好，最大收缩误差为1.5%。结果表明，对于尺寸为ϕ5 0 mm×10 0 mm的圆柱形胶囊，由于其轴向和径向的力臂不同，胶囊的轴向收缩比径向收缩高1.7%。胶囊内的应力偏离均衡状态，导致粉末压坯收缩不均匀、致密化不均匀。当胶囊厚度从2 mm增加到4 mm时，最大径向位移与轴向位移之比从0.47增加到0.75。髋关节过程中的压力传递与胶囊厚度、胶囊材料性能和物理参数有关。
The Shima yield criterion used in finite element analysis for nickel-based superalloy powder compact during hot isostatic pressing (HIP) was modified through uniaxial compression experiments. The influence of cylindrical capsule characteristics on FGH4096M superalloy powder compact deformation and densification behavior during HIP was investigated through simulations and experiments. Results revealed the simulation shrinkage prediction fitted well with the experimental shrinkage including a maximum shrinkage error of 1.5%. It was shown that the axial shrinkage was 1.7% higher than radial shrinkage for a cylindrical capsule with the size of ϕ50 mm × 100 mm due to the force arm difference along the axial and radial direction of the capsule. The stress deviated from the isostatic state in the capsule led to the uneven shrinkage and non-uniform densification of the powder compact. The ratio of the maximum radial displacement to axial displacement increased from 0.47 to 0.75 with the capsule thickness increasing from 2 to 4 mm. The pressure transmission is related to the capsule thickness, the capsule material performance, and physical parameters in the HIP process.
