热等静压法是消除铸件内部缺陷及改善材料性能和铸件其他特性的一种有效方法,通过治愈内部缺陷可以使铸件致密化,改善可焊性,提高力学性能,大大地减少性能的分散度。针对不同材料,热等静压处理过程中的温度、压力的控制以及杂质和化学反应的控制十分复杂,需要大量的经验和技术积累。

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.

Real effect of HIP densification treatment

 

l  通过热等静压处理可以将很多铸件的性能(尤其耐疲劳性)提高到接近甚至超过锻件的水平;

l  Many performances of casting may be improved to the level even higher than that of the forging through HIP (especially fatigue resistance);

l  在等静压的作用下,材料内部孔隙消除的同时能够保持其原有的形状;

l  Under the isostatic effect, at the same time of eliminating the inner pores of the material, the original shape can be maintained;

l  通过热等静压处理可以有效的改善材料塑性及可焊性。

l  Able to effectively improve the ductility and weldability by HIP treatment.
