Manufacturing specification determination method, manufacturing method, and manufacturing specification determination device for metal materials

摘要

To provide a determination method for a production specification of metallic material, a production method of metallic material and a determination device for the production specification, each of which allows for improvement of robustness of metallic material against disturbance at production of the metallic material.SOLUTION: The determination method for the production specification of a metallic material includes the steps of: acquiring at least one actual achievement data determined after a prescribed step during production of the metallic material; and carrying out an inverse analysis based on one or more actual achievement data and a prediction model in which the production specification and material property are connected and searching the production specification after the prescribed process so that the estimate of the material property approaches a desired value progressively.SELECTED DRAWING: Figure 1
