Analysis of Distribution and Diffusibility of Component in Titanium-Steel Interface
-
摘要: 在钛-钢复合过渡接头上采集了界面观察试样, 对钛-钢界面的化合物分布和成分扩散进行了分析。试验结果表明, 钛-钢界面存在熔化金属, 该熔化层极薄, 厚度约0.3μm, 界面内存在纳米晶和非晶的混合组织, 界面及界面附近存在Fe、Ti元素的扩散。Abstract: Samples for interface morphology observing were collected in the titanium-steel cladding transition, and the distribution and diffusibility of component in titanium-steel interface were analyzed.The test results indicated that molten metal existed in titanium-steel interface, and the layer of molten metal was extremely thin, with a thickness about 0.3 μm.Nanocry stalline and the amorphous mixed organization also exists in titanium-steel interface, and pervasion of Fe and Ti elements pervaded in and around the titanium-steel interface.
