Abstract
본 발명은 심가공용 열연강판의 시효성 평가방법에 관한 것이며, 그 목적은 실제 발생되는 시효현상을 실험실적으로 평가하여 시효효과를 분석하고 소재의 사용기준을 정립하고자 함에 있다.The present invention relates to a method for evaluating the aging of hot-rolled steel sheet for deep processing, the object of the present invention is to evaluate the aging phenomenon actually generated experimentally to analyze the aging effect and to establish the use criteria of the material.
본 발명은 심가공용 열연강판의 재질 평가방법에 있어서, 실제 소재가 받은 열이역에 의거하여 이를 log(t)=B+A/T(여기서, t는 시효시간, T는 절대온도, A,B는 상수)으로부터 인공시효조건으로 환산하고, 환산된 인공시효조건별 가공시험을 행하여, 그에 따른 결과에 의해 인공시효조건의 기준값을 설정한 다음, 이를 역으로 자연시효에 해당되는 조건을 구하여 시효성을 판단하는 심가공용 열연강판의 시효성 평가방법에 관한 것을 그 기술적 요지로 한다.In the present invention, in the method for evaluating the material of hot-rolled steel sheet for deep processing, log (t) = B + A / T (where t is an aging time, T is an absolute temperature, A, B is converted into an artificial aging condition from the constant), and subjected to processing tests for the converted artificial aging conditions, the reference value of the artificial aging conditions is set according to the result, and vice versa. The technical gist of the method for evaluating the aging characteristics of hot rolled steel sheets for deep workings is to be evaluated.
