- Additional information
- By implementing a volumetric measure of cavities using small angle neutron scattering (SANS), evolution of creep cavities during creep life was assessed. The impact of plastic pre-strain on promoting early cavity nucleation was also revealed. This is significant, because most laboratory creep deformation tests are undertaken by using applied stresses that are greater than the material yield stress, in order to complete the tests within a practical timescale. Thus, creep deformation and damage models based on conventional uniaxial creep tests innately conflate plastic strain and creep mechanisms.
