【摘要】 应用金相、显微硬度,电子探针及X射线衍射等方法研究了锆-2合金和18-8奥氏体不锈钢之间的扩散结合层和爆炸结合层。确定了结合层中各种相的成分和晶体结构。扩散结合层中可分为四层,其中存在α-Fe、Zr（Fe5/8Gr3/8）₂、Zr₂（F3/4Ni4/4）和α-zr等相,而爆炸结合层中只发现zr（FeCrNi）₂相。并讨论了扩散结合层中各组织的形成规律。更多还原

【Abstract】 The diffusion bonding and explosion bonding between zircaloy-2 and austenite stainless steel have been investigated. Metallography,microhardiness, EPMA and X-ray diffraction were employed to identify the phases in the bonbing zone, and the composition, lattice structure of these phases were also determined.α-Fe, Zr(Fe_5/8Cr_3/8)₂, Zr₂(Fe_3/4Ni（1/4）) and α-Zr phases could be identified in diffusion bonding zone in which four layers existed, whereas in the explosion bonding zone, only Zr（Fe Cr Ni）₂ phase have been Jonup. The regularity of the formation of different microstructures in diffusion bonding zone is discussed.更多还原
