Predictions of ICHAZ cyclic thermo-mechanical response in GTAW process for 9Cr steels
Mac Ardghail, Padraig; Barrett, Richard A.; Harrison, Noel M.; Leen, Sean B. (ASME The American Society of Mechanical Engineers, 2019-02-25)This work is concerned with the development of a modeling framework to predict the effects of tempered–untempered martensite heterogeneity on the thermomechanical performance of welded material. A physically based ... -
A process-structure-property model for welding of 9Cr power plant components: The influence of welding process temperatures on in-service cyclic plasticity response
Mac Ardghail, Padraig; Harrison, Noel M.; Leen, Sean B. (Elsevier, 2019-04-30)A process-structure-property methodology is presented for welding of 9Cr steels under representative flexible operating conditions for a typical thermal power plant girth-welded pipe. The welding-induced evolution of ... -
A review of thermal, microstructural and constitutive modelling of 9Cr steel for power plant applications: Towards a through-process model for structural integrity of welded connections
Mac Ardghail, Padraig; Leen, Sean B.; Harrison, Noel M. (Elsevier, 2020-01-01)Life prediction for 9Cr steel welded components is an important issue facing power plant as it moves from steady-state, base-load operation to transient, flexible operation. Welding and heat-treatment of 9Cr components ...
