【摘要】 研制了一种 Cr6Ni11Mn13 Mo Ti奥氏体钢焊条用于高温服役 ( 4 5 0～ 65 0℃ )的 Cr-Mo钢构件的异种金属焊接 .结果表明 :其异质接头具有良好力学性能和抗氧化性能 ,可以克服以往的异质接头服役过程中因碳迁移而导致的提前失效问题更多还原

【Abstract】 A type of austenitic manual electrode has been developed. These electrodes are used to weld Cr Mo ferritic steels which are in service at 450~650 ℃. The results show that: (1) the dissimilar metal welding joints have good mechanical properties; (2) the failure caused by the carbon migration in the surrounding of the weld interface of the DMWs in service can be overcome.更多还原
