The impactenergies in fuse line (FL) and heat-affected zone were evidently lower than the values of base metals.
熔合线处和热影响区的低温冲击功相比母材均显著降低。
2
Microstructures of weld joints were analyzed and meanwhile corresponding impactenergies at a low temperature were measured.
分析焊接接头的组织,测量了焊接接头的低温冲击功。
3
The dynamic impactenergies of 16MnR welded joints were determined with high speed impact test, and the influencing factors and fracture morphology were studied.
