摘要	The effects of temperature and pressure on density, microstructure and mechanical properties of powder compacts during hot isostatic pressing (HIPping) were investigated. Optimized HIPping parameters of temperature range from 900 to 940 degrees C, pressure over 100 MPa and holding time of 3 h, were obtained. Tensile properties after different heat treatments show that both the geometry of samples and cooling rate have a significant influence on mechanical properties. Finite element method was used to predict the temperature field distribution during HIPped sample cooling, and the experimental results are in agreement with simulation prediction. The interaction of HIPping parameters was analyzed based on the response surface methodology (RSM) in this study.
