| Abstract: |
| Forming mechanism of the residual stress field in the case of carburize quencher is detail expounded.Based on the parameters thermal conductivity coefficient,specific heat,convection coefficient,facies change temperature,specific enthalpy and thermal expansion coefficient etal.which are obtain by experiment,the numerical simulation about the course of carburize with multi time-varying parameters by the finite element software ANSYS,obtain the correspond to data of forming the stress field in the course of carburize and the residual stress field after carburize.The effects of carburize depth on residual stress field are discussed,so providing reliable theory gist for effective controlling the formation of residual stress field. |
