Abstract

According to mocroscopic and microscopic analysis on the fracture it has been proved that the failure of the connecting rods is high-cycle fatigue fracture resulted from stress concentration.The effect of heat treatment on the properties of connecting rods has been discussed through metallographic test,chemical composition analysis and mechanical properties detecting on the connecting rod material.
