MATERIAL ORGANIZATION PREDICT DEVICE, PRODUCT FABRICATION METHOD, AND MATERIAL ORGANIZATION PREDICT METHOD

摘要

A material organization predict device (1) comprises: a temperature calculation unit (103) which, on the basis of a temperature condition for applying a temperature change to a material, calculates temperatures at a plurality of calculation points within a region which is to be calculated of a material; a nucleation iteration calculation unit (104) which, on the basis of the temperatures at the plurality of calculation points, calculates nucleation iterations within the region to be calculated; a nucleation unit (105) which, on the basis of the nucleation iterations, determines from the plurality of calculation points a precipitation phase generation point which generates a precipitation phase nucleus; a grain growth calculation unit (106) which, with respect to the precipitation phase generation point, calculate grain growth in the precipitation phase; and, on the basis of the calculated grain growth of the precipitation phase, predicts the organization of the material.
