不同热处理制度下1Cr11Ni2W2MoV闪光对焊接头的组织与性能
Microstructure and mechanical properties of flash butt welded joints of 1Cr11Ni2W2MoV stainless steel after different heat treatment
摘要
Abstract
Flash butt welding experiments of 1Cr1 1Ni2W2MoV stainless steel are carried out,and then the microstructure and properties of the welded joints with different postweld heat treatments are studied.The results show that flash butt welding is suitable for 1Cr11Ni2W2MoV and can gain the high quality welded joints.The microstructures of flash butt welds of 1Cr1 1Ni2W2MoV are martensite and a small quantity of δ-ferrite,and the welded joints have better tensile property and worse plasticity and impact toughness.After quenching and temper heat treatment,the microstructure is tempered sorbite,and the tensile strength,plasticity and impact toughness of the welded joints are improved.In the condition of quenching at 1 000 ℃ and temper at 570 ℃,the welded joints have excellent integrated mechanical properties.关键词
