不同焊材匹配与时效处理对异种钢焊接接头显微结构与力学性能的影响
Effect of Different Welding Material Matching and Aging Treatment on Microstructure and Mechanical Properties of Dissimilar Steel Welded Joints
摘要
Abstract
The microstructure and mechanical properties of Q235/316L dissimilar steel welding joints were researched by using metallurgical microscope,universal testing machine,impact test enginery,microhardness tester etc.The results showed that microstructure and mechanical properties of dissimilar steel welded joints were improved in the process of Q235/316L dissimilar steel welding,while the A042 was used as a surfacing welding material and the A022 was used as a fill welding material.The performance dissimilar steel welded joints of 300℃ × 2h insulation and air-cooled aging treatment was superior to that of 500℃ × 2h,700℃ × 2h insulation,air-cooled aging treatment and non-aging treatment.It was caused by existence ferrite and pearlite,so,yield strength and tensile strength were greatly improved.At the same time,weld zone and 316L HAZ impact toughness were increased,due to the elimination of hydrogen and reverse change austenite amount of growth.关键词
