     Residual Stresses & Retained Austenite이란?

 

     잔류응력이란 절삭, 압연, 단조, 가열, 냉각, 열 처리, 용접, 도금 등으로 인한 급격한 환경 변화로

     금속이나 세라믹 등에 생기는 불 균일한 소성 변형의 결과로서 금속 내에 발생한 응력( Stress )을

     말한다.  잔류 오스테 나이트( retained austenite )란 담금질된 철강 속에서 오스테나이트 조직의

     일부가 변태되지 않고 남아 있는 것을 말한다.

 

     TEC사에서 생산하여 공급되고 있는 X-Ray Diffraction analysis (XRD) systems은 비교적

     커다란 부분품( large components )들도 섹션( without the need for sectioning )을 나눌 필요가

     없이 바로 측정 분석할 수가 있으며 베어링, 스프링 및 기어등의 잔류 오스테나이트( retained

     austenite :  담금질된 철강 속에서 오스테나이트 조직의 일부가 변태되지 않고 남아 있는 것 )를

     5분 이내에 측정할 수가 있다.
