摘　　要：00Cr22N i5Mo3N双相不锈钢的两相组织结构具有良好的耐蚀性和力学性能,因此在压力容器及集输管道等领域得到了广泛的应用。在00Cr22N i5Mo3N双相不锈钢焊接时,必然要经历热循环过程,虽然该过程变化很快且历时短暂,但往往会导致热影响区相比例和相分布状态的变化,从而影响焊接接头的力学性能和耐腐蚀性能。通过热模拟试验研究,分析了00Cr22N i5Mo3N钢焊接时热影响区的相比例及组织转变规律,为制定和调整焊接工艺提供理论参考依据。Duplex structure of 00Cr22Ni5Mo3N duplex stainless steel takes on well performance in erode resistance and mechanics,which makes it widely used in the fields of pressure vessel and transportation pipeline and so on.During welding 00Cr22Ni5Mo3N duplex stainless steel,the process of heat circle will be involved in consequentially.Although the process is so fast and only takes short time,it always results in variations in structure proportion and distribution,thereby influence the property of mechanics and erode resistance of joint.By heat simulation test,to analyze the variation rule of proportion and structure in HAZ during welding,then it can give theoretical reference for preparing welding process.
