The Establish and Analysis of the Quenching Residual Stress’ Function of the Club-Shaped Metal
With the development of fracturing mechanics, there has been growing recognition that the research on the residual stress of heat treatment becomes attractive. Metal cylinder as the research object, through upbuilding the mathmatic model and sovling the heat conduction equation, whose test data are regarded as the boundary condition can be used to get the distributing temperature function of the workpiece. From this function, it can be deducted the quenching residual stress functions of the club-shaped metal that is resulted from heat stress during quenching. The elastic-plastic transition temperature and elastic modulus which are measuerd can be used to get the calculated value of residual stress by this formula.
