Tension–compression creep asymmetry in a turbine disc superalloy: roles of internal stress and thermal ageing

The tension and compression creep behaviour of an as-received and pre-aged IN100 disc alloy have been characterised in order to validate a previous hypothesis that the unusual response of low and even negative initial creep rates in tension was caused by the presence of an internal stress field with...
