초록

STS 321 스테인리스강은 액체 로켓 엔진을 비롯한 고온 고압의 시스템의 재료로서 많이 사용된다. 321 스테인리스강의 고온에서의 변형 거동을 예측하기 위해 Kocks의 전위 장벽 모델을 근거로 유동응력에 대한 구성 방정식을 열적 응력 요소와 비열적 응력 요소를 사용하여 제안하였다. 제안한 모델은 321 스테인리스강의 상온부터 $500^{\circ}C$의 넓은 온도 영역에서 재료의 변형 거동들을 잘 예측하였다.

STS 321 stainless steel is generally used for a material of high-temperature and high-pressure system including liquid rocket engine. The constitutive equation for flow stress has been suggested using thermal stress component and athermal stress component based on Kocks dislocation barrier model to predict 321 stainless steel's deformation behavior at elevated temperature. The suggested model predicted well the material deformation behaviors of 321 stainless steel at the wide temperature range from room temperature to $500^{\circ}C$.
