热等静压对复杂元件进行扩散连接而保持原形状，并且接缝达到完全的冶金结合。本文讨论了带若干个小孔的厚为０．２ｍｍ的不锈钢薄片的热等静压扩散连接试验，对连接试样的外观及连接界区的显微组织进行了检验，并测定了界区及其附近母体的显微硬度。结果表明，在压力１１２ＭＰａ左右，温度为１０５０℃左右，保持３ｈ的条件下，可使不锈钢片之间达到冶金结合，有跨界面新晶粒生成，接缝处的显微硬度与母体相似，并且小孔仍然保持通畅。
Hot isostatic pressing diffuses and joins complex components while maintaining their original shape, and the joint achieves complete metallurgical bonding. In this paper, the hot isostatic pressing diffusion test of 0.2mm thick stainless steel sheet with several small holes is discussed. The appearance of the test specimen and the microstructure of the connection zone are tested. Near the parent’s microhardness. The results show that under the pressure of about 112MPa and the temperature of about 1050 ℃ for 3h, the stainless steel sheets can be metallurgically bonded with the formation of new interlamellar grains. The microhardness of the joint is similar to that of the matrix, And the hole remains unobstructed.
