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.
