用金相、显微硬度,扫描电镜、X 射线能谱及 X 射线衍射等方法研究了钛和18/8不锈钢之间的扩散结合层和爆炸结合层。确定了结合层中各相的成份和晶体结构。扩散结合层中分为六层,它们是靠近不锈钢侧的α—Fe、Fe_(35)、Cr_(13)、Ni_3、Ti_7和 Ti(Fe_(0.75)Cr_(0.15)Ni_(0.1))_2三层和靠近Ti 侧的β一Ti 和含有 Fe、Cr、Ni 的α—Ti 两层,在这之间是一层液相凝固层,其中又有 Ti(Fe_(0.81)Cr_(0.13)Ni_(0.06))和β一Ti 两相。爆炸焊熔区的成份大约相当于钛与不锈钢以1∶1混合而成,其中主要的相是 Ti(Fe_(0.75)Cr_(0.15)Ni_(0.1))_2。本文并讨论了各相层的形成规律。
The diffusion bonding layer and the explosive bonding layer between titanium and 18/8 stainless steel were studied by metallography, microhardness, scanning electron microscopy, X-ray diffraction and X-ray diffraction. The composition and the crystal structure of each phase in the binding layer were confirmed. Diffusion bonding layer is divided into six layers, which are α-Fe, Fe_ (35), Cr_ (13), Ni_3, Ti_7 and Ti (Fe_ (0.75) Cr_ (0.15) Ni_ (0.1) Layer and a Ti-Ti layer containing Fe, Cr and Ni close to the Ti side and a liquid-phase solidified layer having Ti (Fe_ (0.81) Cr_ (0.13) Ni_ 0.06)) and β-Ti two phases. The composition of the explosive zone is roughly equivalent to a 1: 1 mixture of titanium and stainless steel, with the main phase being Ti (Fe_ (0.75) Cr_ (0.15) Ni_ (0.1)) _2. This article also discusses the formation of each phase of the law.
