多道焊缝
By using the thermo-simulation and Charpy-V notch impact test along with observation of the microstructures in the cleavage crack is initiated, the effect of manganese on the toughness of various zones in C-Mn multipass weld metals is investigated.
本文通过热模拟、夏氏冲击及启裂源组织观察等实验,研究了锰对C-Mn钢多层焊缝韧性影响的机理。
By using thermo-simulation, Auger analysis and Charpy V impact test and with observation of the microstructures in which the cleavage crack initiated, the morphology and toughness of the local brittle zone of C-Mn and Cr-Ni-Mo multipass weld metals have been investigated.
以C-Mn,Cr-Ni-Mo手工多层焊缝为研究对象,采用示波冲击,俄歇分析,启裂源组织观察及热模拟实验,对薄弱环节组织的形态,韧性及对焊缝韧性的影响进行了研究。
