利用光学显微镜、扫描电子显微镜、X射线衍射仪、透射电子显微镜、显微硬度计和拉剪实验,研究不同热处理温度对钛-钢爆炸轧制复合板界面组织特征和性能的影响。热处理温度为650、750、850、950°C,保温时间为60 min。结果表明:热处理过程加速界面元素扩散和组织的转变。随着温度的升高,复合板剪切强度下降。在850°C及以下温度热处理时,扩散反应层形成化合物TiC,剪切强度下降缓慢。当热处理温度超过850°C时,扩散反应层形成大量的Ti-Fe金属间化合物(Fe2Ti/FeTi)及少量的TiC,剪切强度明显下降。

The effect of heat treatment on microstructure and mechanical properties of the Ti-steel explosive-rolling clad plate was elaborated by optical microscopy (OM), scanning electron microscopy (SEM), X-ray diffraction (XRD), transmission electron microscopy (TEM), micro-hardness test and shear test. The composites were subjected to heat treatment at temperature of 650-950 °C for 60 min. The results show that the heat treatment process results in a great enhancement of diffusion and microstructural transformation. The shear strength decreases as the treatment temperature increases. Heated at 850 °C or below, their shear strength decreases slowly as a result of the formation of TiC in the diffusion interaction layer;while at the temperature of 850 °C or above, the shear strength decreases obviously, which is the consequence of a large amount of Ti-Fe intermetallics (Fe2Ti/FeTi) along with some TiC distributing continuously at diffusion reaction layer.
