A micromechanical model at the microscale within a crystal plasticity self-consistent model (SCM), is used to analyse loading histories in Type 316H stainless steel, common to structural components in high-temperature power plants. The study compares the SCM predictions on changes in mechanical behaviour and creep properties to analyses via the UK’s R5 structural assessment code. Plant-relevant cyclic-creep histories in Type 316H stainless steel at 550°C are examined with focus on the…
