Investigation of the grain deformation to orthogonal cutting process of the textured Alloy 718 fabricated by laser powder bed fusion (2023)
Journal Article

In the laser powder bed fusion (LPBF), the grains grow in preferential directions depending on the scanning strategies, which results in layer-by-layer builds of particular crystallographic textures. The unique microstructure formed by LPBF results i...

What can micromechanics tell us about the surface integrity of shot-peened materials? (2023)
Journal Article

Standard techniques for assessing shot peening include XRD and EBSD for measuring residual stresses and severe deformation beneath the surface; however, these techniques do not consider the localised micromechanical behaviour. Here, single-grain micr... Read More about What can micromechanics tell us about the surface integrity of shot-peened materials?.

Tailorable shielded compliance of thermal barrier coatings through laser texturing and microstructural modification: microfeature design and validation (2023)
Journal Article

Thermal barrier coatings (TBCs) are widely used for protecting components from an aggressive environment and excessive temperatures. However, the top coat can lack thermal compliance and environmental resistance, promoting premature failure. This stu...

Fractal Analysis on Machined Surface Morphologies of Soft-Brittle KDP Crystals Processed by Micro Ball-End Milling (2023)
Journal Article

The micro-defects on KH2PO4 (KDP) optic surfaces are mainly repaired by the micro-milling technique, while it is very easy to introduce brittle cracks on repaired surfaces, as KDP is soft and brittle. To estimate machined surface morphologies, the co... Read More about Fractal Analysis on Machined Surface Morphologies of Soft-Brittle KDP Crystals Processed by Micro Ball-End Milling.

A rational approach to beam path planning in additive manufacturing: the inverse heat placement problem (2023)
Journal Article

High demand for components with complex geometries at macro and micro levels drives the development of additive manufacturing (AM). However, the scientific basis for designing energy beam scanning strategies (e.g. beam scanning speed, beam path, beam...
