Prediction of microstructure evolution for additive manufacturing of Ti-6Al-4V
(Elsevier, 2020-04-26)
A key challenge for successful exploitation of additive manufacturing (AM) across a broad range of industries is the development of fundamental understanding of the relationships between process control and mechanical ...
Dual-phase cohesive zone modelling and experimental validation for hydrogen-assisted cracking of 2205 duplex stainless steel
(Elsevier, 2021-01-01)
The hydrogen-assisted cracking (HAC) behavior of 2205 duplex stainless steel is investigated via experimental testing and computational modelling, with specific focus on developing a predictive methodology for the coupled ...
Effect of welding on microstructure and mechanical response of X100Q bainitic steel through nanoindentation, tensile, cyclic plasticity and fatigue characterisation
(Elsevier, 2020-12-30)
This paper presents an experimental characterisation of fatigue at welded connections for the next-generation high-strength low-alloy offshore riser steel, X100Q. An instrumented girth weld is conducted with a parallel ...
A physically-based method for predicting high temperature fatigue crack initiation in P91 welded steel
(Elsevier, 2021-08-27)
A methodology is presented for physically-based prediction of high temperature fatigue crack initiation in 9Cr steels, with a focus on material inhomogeneity due to welding-induced metallurgical transformations. A modified ...
A dislocation mechanics constitutive model for effects of welding-induced microstructural transformation on cyclic plasticity and low-cycle fatigue for X100Q bainitic steel
(Elsevier, 2020-12-14)
This paper presents a physically-based cyclic viscoplasticity model to capture the influence of welding-induced microstructural transformation on the fatigue response of the bainitic high-strength low-alloy steel, X100Q. ...
Towards a process-structure model for Ti-6Al-4V during additive manufacturing
(Elsevier, 2020-12-15)
This paper presents the development of an integrated approach for microstructure prediction in laser beam powder bed fusion (PBF-LB) manufacturing of Ti-6Al-4V, primarily focused on the solidification morphology and ...
