Title:
METHOD FOR EVALUATING STRUCTURAL CHANGE DURING PRODUCTION PROCESS, AND ANALYSIS PROGRAM
Document Type and Number:
WIPO Patent Application WO/2016/092615
Kind Code:
A1
Abstract:
Changes in isotopic distribution over time are evaluated by artificially introducing areas having different isotopic ratios into a metal material before sintering, heat treatment, and grain boundary diffusion, and comparing atom probe analysis results before and after the sintering, heat treatment, and grain boundary diffusion.
