Abstract
This paper studies the multiaxial creep–fatigue life for type 304 stainless steel at elevated temperature. Strain controlled biaxial tension–compression creep–fatigue tests were carried out using cruciform specimens under four strain waves at three principal strain ratios. The strain wave and the principal strain ratio had a significant effect on creep–fatigue life of the cruciform specimen. The creep–fatigue life ratio decreased as the principal strain ratio increased which indicates that larger creep damage occurred at larger principal strain ratio. The effects of the strain wave and principal strain ratio were discussed in relation to the observations of surface crack and void area density in the gage part of the specimen.
