摘　　要：借助金相显微镜、能谱议等手段,分析Gleeble-1500热模拟试验机循环累积变形复合后的Ti/Q235复合试样的界面组织、相结构和成分变化。结果表明,Ti/Q235在800℃以上900℃以下用循环累积变形复合的方法进行压制时,界面附近出现明显的过渡区域,但界面又不会有较明显的脆性相,影响结合强度。在850℃进行较低速率,多道次轧制,大的累积压下量的工艺方法,不会使结合界面处的脆性物质增加而明显降低结合强度。The interface characteristic of TA1/Q235 composite sample by cyclic accumulated deformation process with Gleeble-1500 thermal analog testing machine, such as interface structure, phase composition and components diffusion are analyzed by means of metallographic microscope, energy spectrometer etc. The results show that remarkable transitional zones are discovered on the interface of Ti/Q235 composite sample after cyclic accumulated deformation process at 800℃-900℃, however there is no obvious brittle substance which is adverse to the bond strength. The brittle substance on the interface is not increased when the composite sample is pressed time after time with low speed at 850℃.
