| 摘 要： | 采用钨极氩弧焊方法(GTAw),在奥氏体不锈钢基体上堆焊Fe3Al合金,考察焊接电流和预热温度等工艺参数对堆焊试验结果的影响.研究表明,工艺参数的改变对能否获得F3Al合金堆焊层有较大的影响,裂纹是堆焊Fe3Al合金时出现的主要缺陷.基于试验结果,对试验参数进行优化,得到一套在工程上行之有效的堆焊工艺及参数,并对该工艺参数下所获得的堆焊层的显微组织、相构成和显微硬度进行检测分析.

| Abstract: | The Fe__3Al alloy was overlaid on austenite stainless steel by the use of gas argon welding process,and the effect of such parameters as welding current and preheating temperature on the experiment result was also studied. Results show that the alteration of parameters has a great influence on whether Fe__3Al overlayer can be obtained or not. Cracking is the major flaw in this experiment. Based on the results,the optimized welding parameters and process which will be effective in engineering were presented,and the microstructure,phase and microhardness of the obtained overlayer under optimal conditions were investigated. |
