【Abstract】 A series of complicated,expensive experiments have to be carried out for selection of a suitable material and for designation of heat treatment process parameters of heavy section work piece.However,the numerical simulation can simplify and shorten this process.The simulation calculations of the microstructures and properties for die blocks with different materials and sizes after the heat treatment were carried out by statistical mathematics on the basis of experimental study by other researchers.The results show that the calculation values are agreed with the test values,and it may be used in designations of heat treatment process for heavy section work pieces.更多还原
