【Abstract】 The transient temperature field in the process of heat treatment of metal material when considering phase transformation is analyzed by means of boundary element method.The nonlinear is reduced by using Kirchhoff’s transformation.The scattering of the boundary integral equation and numeric al technology are described in detail.The method of dissectting one unit into other units to treat the unusual integral is presented.The result shows that the method provided in this paper is effective.更多还原
