| 1 | A review of friction stir welding of steels: Tool, material flow, microstructure, and properties显示文摘Considerable progress has been achieved in friction stir welding(FSW) of steels in every aspect of tool fabrication, microstructure control and properties evaluation in the past two decades. With the development of reliable welding tools and precise control systems, FSW of steels has reached a new level of technical maturity. High-quality, long welds can be produced in many engineering steels. Compared to traditional fusion welding, FSW exhibits unique advantages producing joints with better properties. As a result of active control of the welding temperature and/or cooling rate, FSW has the capability of fabricating steel joints with excellent toughness and strength. For example, unfavorable phase transformations that usually occur during traditional welding can be avoided and favorable phase fractions in advanced steels can be maintained in the weld zone thus avoiding the typical property degradations associated with fusion welding. If phase transformations do occur during FSW of thick steels, optimization of microstructure and properties can be attained by controlling the heat input and post-weld cooling rate. | F.C. Liu Y.

| 10 | AN EXPERIMENTAL-NUMERICAL METHOD FOR MEASURING CRACK PROPAGATING VELOCITIES UNDER STRESS WAVE LOADING显示文摘An experimental-numerical method for measuring dynamic crack propagating veloc-ities under stress wave loading is established in this paper. The experiments of thethree-point bend specimen are done on the improved Hopkinson bar. Deflection ofloading point, dynamic load and instantaneous crack length ave measured, then crackpropagating velocities are calculated. Experiments on 40Cr steel show that the resultsgiven by this method have a good agreement with that obtained by the resistance frac-ture gage method. Therefore this method is feasible for measuring crack propagatingvelocities under high loading rate and will have wide application. | G.Y. Sha, F.C. Jiang D. Wang, D.K.
