Analysis on Fracture Phenomenon of Travelling Wheel Made by 65Mn
In allusion to the fracture phenomenon of the travelling wheel made by 65Mn,the quenching process,hardness,chemical composition and microstructure and other elements were analyzed.The results show that there are presence of large amounts of carbide eliquation,and companied by shrinkage and inclusions.The reason of defect microstructure was analyzed.The carbide eliquation is the reason of fracture.
