通过对15锰钒氮钢的基材试样和模拟焊接热影响区热循环过程处理的试样进行了氮化物相和钒相的分析对比,结果表明:固溶氮和固溶钒在这两种试样中有显著的差别,可以推测15锰钒氮钢经过焊接后,热影响区的材质起了变化,此种变化不容忽视,应选择合适工艺,予以克服。 The comparison of the nitride phase and the vanadium phase was carried out on the substrate samples of 15 Mn-V-N steel and the samples treated by the thermal cycling process in the simulated heat-affected zone of heat treatment. The results show that the solid solution nitrogen and the solid solution vanadium are in these two There are significant differences among the samples. It can be inferred that the material of heat-affected zone has changed after the welding of 15 Mn-V-N steel. Such changes should not be neglected. Appropriate processes should be selected and overcome.
