The physical characteristics of Ni-based superalloy powder with different particle sizes produced by plasma rotation electrode process( PREP) and the microstructure and mechanical properties of P / M superalloy products were investigated. The experimental results show that the optimum powder particle sizes should be in the range of 50-100 μm or 50-150 μm,which can reduce production cost,simplify process and guarantee P / M product quality.
