REMAINING LIFE EVALUATION METHOD AND DEFORMATION AMOUNT EVALUATION METHOD FOR METALLIC MATERIAL

摘要

PROBLEM TO BE SOLVED: To provide a remaining life evaluation method and a deformation amount evaluation method for a metallic material that can stably evaluate a life and a deformation amount of material with high accuracy over a wide range.;SOLUTION: A crystal orientation distribution measuring means measures crystal orientation distribution to the progress degree of a material life of a test material, and crystal orientation distribution quantifying means quantify the crystal orientation distribution. Master curve deriving means derive a first master curve that indicates the relationship between the quantified crystal orientation distribution and the progress degree of the material life, and stores it in a database. The crystal orientation distribution measuring means then measures the crystal orientation distribution of an inspection material for remaining life evaluation, which is formed of the same material as the test material, and the crystal orientation distribution quantifying means quantifies the crystal orientation distribution. Remaining life determining means read the data of the first master curve stored in the database, and applies the crystal orientation distribution of the quantified inspection material to the first master curve to determine the remaining life of the inspection material.;COPYRIGHT: (C)2009,JPO&INPIT
