Friction welding weldability test about titanium alloy TC4(Ti 6Al 4V) was done in detail.Concerning the optimum selection of the parameters,the feature of the TC4 alloy friction welding process was recounted and the mechanical properties and structure of the joint was analyzed.The test result shows that TC4 alloy has good weldability.Without particular protection step,good welded joint can be gotten by means of optimum technological parameters.Because TC4 alloy has low heat conductivity,high heat plasticity and good oxidability,low welding parameters should be selected.The hardness of the weld area is a little lower than that of the base metal.The tension specimen was broken on the base metal.Fracture of tension and impact test show obviously tough break characteristic.With the optimum parameters,equal strength and equal plasticity or even high strength and high plasticity friction welded joint of TC4 alloy can be gotten.The weld area of the joint are closely woven and netted structures.The transitional zone between the weld area and the base metal is double stated structures.

Good and durable hot top is very important for quick production of high quality seamless steel tubes. In order to improve the quality and to develop new kind of hot top in China, we explore experimentally the characteristics of friction welding joint of TZM Mo-base powder alloy and H11 mold steel. Table 2 lists the friction welding parameters of TZM Mo-base powder alloy and H11 mold steel used in our experiments. We performed microstructure analysis of the joints tested (subsection 2.2), determined distributions of chemical elements in friction welding joints with electronic probe (subsection 2.3), and determined hardness distributions of joints as given in Fig.5. As expected, the difference of wear resistances and that of thermal strengths of the two materials cause the initial friction surface, which joins TZM Mo-base powder alloy with H11 steel, to shift to the final friction surface well within the interior of H11 steel (Fig.2). Also, as expected, the coupled thermo-mechanical action favors grain refinement and the closure of holes in Mo-Base TZM alloy at and near the weld. We emphasize that using hard friction welding parameters is conducive to obtaining high-quality friction welding joint.

The fricton coeficient is an important parameter of energy and tribology.The single crystal superalloy DD3 and powder metallurgy superalloy Renē95 are respectively the blade and disk material to make the blisk of aeroengine.In order to research the friction weldability,the mechanical parameters of friction weld zone are theoretically analysed,and the temperature of friction interface,friction torque and axial prossure during friction welding of DD3 and Rene95 are detected in real time using the computer detected and control system.The method of messuring the temperature is the semi nature thermocouple method.The follow formulations are regressed by mathematic statistics: the friction coefficient at the initial friction stage f 1=1.768 p -0.465 ( T -273) 0.005 ,the flow stress and equivalent friction coefficient at the quasi steady stage σ =186.23exp167.156 T- 273 and f 2 =- 9.293 +0.016 T -6.918×10 -6 T 2.These results are the foundation of analyzing heat mechanism and numerical simulating the process of blisk friction welding.

摩擦系数是摩擦焊接研究中重要的能量参量与摩擦学参量。DD3合金和Ren叆95合金分别是先进航空发动机整体叶盘制造中所用的单晶叶片材料和粉末冶金涡轮盘材料。为研究这两种材料的摩擦焊接性 ,作者在理论推导摩擦焊合区力学参量的基础上 ,采用计算机测控系统实时测量了DD3和Ren叆95连续驱动摩擦焊接过程中的摩擦界面温度、摩擦扭矩与轴向压力。其中 ,摩擦界面温度采用半自然热电偶测量。通过试验数据回归分析 ,分别建立了初始摩擦阶段摩擦系数公式f1=1.76 8-0 .465(T -2 73) 0 .0 0 5、准稳定摩擦阶段的流动应力公式σ =186 .2 3exp 16 7.15 6T - 2 73和等效摩擦系数公式 f2 =- 9.2 93+0 .0 16T - 6 .918× 10 -6T 2 。为进行整体叶盘摩擦焊接过程的产热机制分析与数值模拟奠定了试验基础。
