综合了粉末冶金和锻造的最好特点,热等静压可以生产密度为100%的复杂形状的另件。此外,它能“治愈”铸件中的缺陷,并提高其机械性能。热等静压基本上是使用高温高压压制材料的一种方法。把通常装在包套内的工件置于高压釜中,在热和压力的作用下,“生长在一起”。热等静压消除了普通的金属粉末和锻造技术的许多局限性,并发挥了它们的某些优点。
Combined with the best features of powder metallurgy and forging, hot isostatic pressing can produce parts of complex shapes with a density of 100%. In addition, it can “cure” defects in castings and improve their mechanical properties. Hot isostatic pressing is basically a method of pressing materials using high temperature and pressure. Workpieces, usually housed in envelopes, are placed in autoclaves and “grown together” under heat and pressure. Hot isostatic pressing eliminates many of the limitations of conventional metal powder and forging techniques and exerts some of their advantages.
