摘要
材料是科技发展的基石,金属在材料领域占有重要的地位,而高端金属材料的制备离不开一项专有技术——热等静压。热等静压过程一般没有液相出现,在固态下实现原子间的扩散,进而实现冶金结合。热等静压按照加工原理分为致密化处理、扩散连接和粉末冶金三类应用,其中近终成形是粉末冶金应用的高端形式。归纳总结了热等静压技术的研究进展,分别对致密化处理应用领域、扩散连接应用现状、粉末冶金制品的应用趋势进行了阐述,为寻求高端金属材料制备手段的工程技术人员提供参考。
Metals occupy an important position in the field of materials which are regraded as the cornerstone of the development of science and technology. One specific technology—Hot Isostatic Pressing(HIP), is inevitably related to the production of advanced metal materials. In HIPing process, no liquid phase appears, and metallurgical bonding is achieved due to atomic diffusing in solid state. According to the processing characteristics, HIP can be applied in three scenarios: densification treatment, diffusion bonding and powder metallurgy, in which the HIP near net shape(HIP-NNS) technology is deemed as the high-end form. This paper summarizes the research progress of HIP technology, and describes the application fields of densification treatment, the state-of-the-art of diffusion bonding and the application trends of powder metallurgy products, thereby providing reference for engineering technicians who seek high-end metallic material technology.
