초소성변형거동의 온도의존성에 대한 이론 및 실험적 고찰
Theoretical and Microstructural Study on the Temperature Dependence of Superplastic Deformation Behavior
초록
A series of load relaxation tests was performed to determine stress-strain rate curves at high temperatures. Constitutive parameters of GBS and GMD were evaluated from the curves using the recently proposed inelastic deformation theory. Tensile tests and Microsturcture investigations showed deformation behavior as the relaxation test results predicted.
