摘　　要：采用GLEEBLE热模拟高温拉伸试验方法,对焊接材料ER2209的两种不同铁素体含量的电渣精炼钢锭高温性能进行了研究。通过试验确定了该材料的最佳塑形温度区间,铁素体比例对该种材料的热塑性有较大的影响。The thermoplasticity of ER2209 duplex stainless steel welding material was studied by GLEEBLE high temperature tensile test,and the performance at high temperature was contrasted between two different content of ferrite cast ER2209.The optimal temperature range of cast ER2209 for thermoplasticity was found.The thermoplasticity was greatly effected by the content of ferrite in ER2209.

关 键 词：ER2209 热塑性 高温拉伸
