Microstructure and Strength of HIP Sintered Ni Base Superalloy Using PREP Powder

As the material of turbine discs for the civil airplane, PM (powder metallurgy) superalloys have been in practical use. This is because the advantages of PM superalloys are more pronounced in homogeneous structure, mechanical properties and yield rate than the disadvantage in the cost of the process...
