HIP process is performed to increase fatigue and creep resistance of nickel-based superalloys. Using this process, mechanical properties, particularly creep strength, fatigue strength, and toughness, are improved by four times. Range of temperature, pressure, and time of HIP depends on alloy type and the expected properties. Thus, the proper selection of temperature, time, and pressure of HIP process is very crucial for achieving favorable properties. In this paper, the range of temperature, pressure, and time in the HIP process is specified to achieve the maximum mechanical properties for the widely used nickel-based superalloys. ©2015 Elsevier Ltd.
