Title:
HEAT TREATMENT ANALYSIS METHOD AND DEVICE, PROGRAM, AND RECORDING MEDIUM
Document Type and Number:
WIPO Patent Application WO/2020/138294
Kind Code:
A1
Abstract:
In this heat treatment analysis method, a transformation rate curve of an isothermal transformation diagram is approximated and obtained for each metal structure of a steel material by means of a function of equation (1) in the calculation of a material parameter of the steel material, and a material parameter of a KJMA equation is calculated by using a function of the obtained transformation rate curve. According to this method, the heat treatment analysis can be easily performed with high reliability by enabling phase transformation characteristics to be introduced in a short working time at high accuracy without depending on the subjectivity of a worker.
