Th. Hyde et al., APPLICATION OF THE REFERENCE STRESS METHOD FOR INTERPRETING IMPRESSION CREEP TEST DATA, Materials at high temperatures, 13(3), 1995, pp. 133-138
Impression creep tests have been performed on a 316-stainless steel at
600 degrees C, for which conventional uniaxial creep test data are av
ailable. It is shown that the technique, based on the reference stress
approach, for converting impression creep test data to equivalent uni
axial creep data, is accurate. The results show that the impression cr
eep technique can be used for obtaining creep properties for materials
which have high creep resistance at high temperature and test pressur
e conditions. The difficulties and limitations associated with such si
tuations are described and methods of dealing with them are outlined.
