SC6 35 0型汽车半轴采取摩擦焊接方式制成 ,焊后须进行适当的热处理以改善焊缝区的力学性能。研究了半轴焊后和热处理后的力学性能、组织结构、断裂形态和相区成分 ,分析了半轴热处理后韧性偏低的原因
The semi-shafts of SC6 35 0 type are made by friction welding. After welding, appropriate heat treatment shall be carried out to improve the mechanical properties of the weld zone. The mechanical properties, microstructures, fracture morphology and phase components after half-shaft welding and heat treatment were studied. The reasons for the low toughness after half-shaft heat treatment
