Macro- and micro-scale modelling of material inhomogeneity for the premature failure of welded 9Cr steels in power plants
(NUI Galway, 2019-02-15)Chromium-molybdenum steel pipe (9Cr-1Mo steel) is an important high temperature construction material for welded steam piping networks in gas-fired power plants. A major global problem of such materials is the premature ... -
Microstructural functionally graded Ti-6Al-4V via advanced laser-based technologies
(NUI Galway, 2021-11-10)Functionally graded material (FGM) is characterised by an intended spatial variation in material attributes within a single part. This thesis is focused on advanced laser-based manufacturing technologies of microstructural ... -
A physically-based process-structure-property model for additively manufactured materials
(NUI Galway, 2022-04-27)Successful application of additive manufacturing (AM) across a broad range of industries requires stable and predictable performance of AM materials. However, the microstructure and properties of AM parts vary widely based ... -
A Study of Microstructure-Sensitive Crack Nucleation and Wear in Fretting
(2013-07-08)This thesis presents the development of a computational and experimental methodology for predicting crack initiation and wear in fretting of engineering materials. A bridge-type fretting fatigue test rig is designed and ...
