Since the introduction of the hot isostatic pressing (HIP) technology, it has been widely used in the powder metallurgy forming to improve the densification of castings. With the increasing demand for the high performance nickel-based single crystal superalloys, the applications of the hot isostatic pressing in the nickel-based single crystal superalloys attracted more and more studies. This paper reviews the current research progress in the applications of the hot isostatic pressing for the high temperature nickel-based single crystals, focusing on the elimination effect of the hot isostatic pressing on the looses and other pore defects in the nickel-based single crystal superalloys, and the pore healing mechanism, as well as the changes in mechanical properties such as tensile strength, endurance, and fatigue after applying the hot isostatic pressing. The application of the hot isostatic pressing for the restoration of the mechanical properties of the serviced parts and the calculation simulation in guiding the heat and other topics are also discussed. The role of the static pressure process research, and the future development of China's hot isostatic pressing technology are commented.
