Thickness and Temperature Effects on the J-Integral COD Relationship.

Abstract

The fracture surfaces of compact tension (CT) specimens of HT-9 martensitic stainless steel previously tested at room temperature and at 200 degrees C have been examined by scanning electron microscopy (SEM) to characterize the failure processes and establish correlations with fracture toughness properties; the fracture toughness of HT-9 for two specimen thicknesses (2.5 and 12.7 mm) was determined by conducting J-integral tests using the single specimen unloading compliance method.
