Metallic material design support method, predictive model generation method, metallic material manufacturing method, and design support device

摘要

We provide a design support method that enables accurate prediction values to be obtained while considering the manufacturing conditions of metal materials and can reduce the time load required for design. The design support method according to the present invention is a design support method that supports the design of a metal material having desired properties by a computer, and obtains design conditions including component composition and manufacturing conditions of the metal material and characteristic values of the metal material. A search step that searches for a design condition that obtains the desired characteristic using a prediction model that is constructed based on the associated past performance data and predicts the characteristic value from the design condition, and a search step that searches for the desired characteristic. Among the design conditions corresponding to, the design conditions are set so as to reduce the variation of a plurality of predicted values based on a plurality of different training data sets in the search step, including a presentation step for presenting at least the component composition and the production conditions.
