Chapter 6: Creep Fundamentals – testing methods and traditional analysis

• Uniaxial, biaxial, multiaxial testing and analysis – with emphasis on delayed elastic strain actually measured

• Constant deformation rate and constant strain-rate (closed-loop controlled)

• Creep curves – primary, secondary (transitional) and tertiary behaviours

• High-temperature diffusional creep and Dislocation creep

• Minimum creep rate and its `presumed` engineering importance

• Creep Fracture and minimum creep rate - equations developed for engineering applications

• Is minimum creep rate a fundamental property? Challenging this old concept.

Chapter 7: Creep Modelling

• Traditional dislocation creep based – their limitations (no grain-size effects)

• Newer grain-boundary shearing (GBS) induced primary creep (grain size and structure dependency)

• Primary creep, GBS and GBS-induced Dlayed-Elastic Strain (DES)

• Development of Elasto-Delayed Elastic-Viscous (EDEV) model

• EDEV to explore primary creep and DES (no significant contributions from dislocation creep)

• Secondary creep without cracking – dominated by dislocation creep

Chapter 8: High-temperature grain-boundary embrittlement and creep

• Dislocation pile –up model for crack initiation

• Grain-boundary shearing (GBS) induced crack initiation

• GBS-based kinetics of grain-boundary microcracking and multiplication

• Prediction of volumetric change or dilatation

Chapter 9: GBS-induced crack-enhanced creep and EDEV base models

• Modelling of constant-stress primary, tertiary creep and creep fracture failure and their temperature dependence

• Modelling of minimum-creep rate and its grain-size dependence

• Modelling of strain-rate and stress-rate dependence of compressive strength

• Modelling of constant-strain rate 0.2% yield and upper yield failure, and their rate sensitivity

• Modelling low-cycle fatigue (LCF) and dwell-fatigue

• Welding and heat-affected zone

Chapter 10: High-temperature stress relaxation

• EDEV-based modelling of constant strain stress relaxation

• Modelling effect of initial strain and temperature

• Quantitative Prediction of the contributions due to viscous strain and DES that can be examined experimentally

• Experimental verification using Ti-6246, a titanium-based high-temperature superalloy
