熱等靜壓法是消除鑄件內部缺陷及改善材料性能和鑄件其他特性的一種有效方法，通過治愈內部缺陷可以使鑄件致密化，改善可焊性，提高力學性能，大大地減少性能的分散度。針對不同材料，熱等靜壓處理過程中的溫度、壓力的控制以及雜質和化學反應的控制十分復雜，需要大量的經驗和技術積累。
As a kind of method to eliminate the internal defects of castings and improve the material properties , HIP densification, can improve the weldability, enhance mechanical properties and greatly reduce the degree of dispersion properties of material. When applied to different materials, because different HIP processes are needed, the control of temperature and pressure as well as the impurities and the chemical reaction becomes very difficult. Hence enough technology experiences are necessary.
