A transition from grain- to twin-boundary cavitation was observed in Type 304 stainless steel specimens aged at 593 and 649/sup 0/C (1100 and 1200/sup 0/F) and creep tested at 593/sup 0/C (1100/sup 0/F) and 207 MPa (30 ksi). Evidence of twin-boundary cavitation was also observed in unaged specimens tested at 649/sup 0/C (1200/sup 0/F) and 193 MPa (28 ksi). This same behavior was also found in aged Type 316 stainless steel. Several possible reasons have been suggested for the absence of frequently observed grain-boundary cavitation and its transition to twin-boundary cavitation.
