Abstract
Aiming at the fault coupler knuckle of a railway vehicle, the paper conducts a fracture analysis, and makes some detection including coarse grains of nonmetallic impurities in the original structure of the coupler knuckles, metallographic structure of the repaired welds and cross section, matrix structure and hardness of the coupler knuckles. The results show that coarse grains of nonmetallic impurities in the original structure of the coupler knuckles are so large without good treatment;and that tiny cracks exist even after welding, with unsatis fying ability to resist cracks, which is the main reason of cracks.关键词
