Abstract

사용중인 중화학 설비의 재료물성의 경년열화적 특성을 평가하기 위하여 기존 실험법의 인장시험편이나 충격시험편을 채취하기는 실제적으로 불가능하다. 인장강도등 인장특성과 비교한 결과 인장강도, 연신율, 항복강도, 종탄성계수와 소형펀치실험의 각 특성과 선형적 관계를 얻을 수 있었다. 또한 경년열화도를 평가하는 두구인 파면천이온도(FATT)와 비교하기 위하여 저온 소형펀치실험을 실시한 결과 충격실험을 통하여 구한 FATT온도와 소형펀치실험의 천이온도 ( $T_{sp}$ )와 일정한 관계가 있음이 밝혀져 사용재의 열화도를 평가할 수 있다.
