Abstract:On the base of experiment data,BP network is used to construct the model of relationship between the mechanical properties and the chemical elements as well as the temperature of heating treatment in high Co Ni secondary hardening steel.We put forward that the mechanical properties of steel can be taken as the inputs of network,the chemical elements and the temperature of heating treatment can be taken as outputs of network.According to the request for the mechanical properties,we design the content of chemical elements and the condition of heating treatment.This method can overcome the shortcomings of great computation time and easily running into local optimization of the other methods.It provides a theoretical assistant method for the design of high performance material.
Keywords:secondary hardening steel  artificial neural network  design of material
