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.
