Modelling and experimental study of laser-assisted milling of fibre reinforced SiC/Ti-6Al-4V metal matrix composite (2023)
Journal Article

Metal matrix composites (MMCs) offer unique advantageous mechanical properties by strengthening a ductile metal matrix with a ceramic reinforcement (e.g., Ti6Al-4 V/SiCf). However, their heterogeneous composition poses machining challenges including...

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...

Improving generalisation and accuracy of on-line milling chatter detection via a novel hybrid deep convolutional neural network (2023)
Journal Article

Unstable chatter seriously reduces the quality of machined workpiece and machining efficiency. In order to improve productivity, on-line chatter detection has attracted much interest in the past decades. Nevertheless, traditional methods are inevitab...

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?.

Inverse size effect and deformation mechanism in Ti-6Al-4V cutting process – investigation on effect of bimodal microstructure on machining (2023)
Journal Article

Ti-6Al-4 V finds wide applications in industrial areas due to its unique properties. Though, how its special microstructure (i.e., properties mismatch between different phases) could influence the surface/chip formation mechanism when machining (e.g....

The effect of high strain rate impact in Yttria stabilized zirconia (2023)
Journal Article

Yttria stabilized zirconia (6-8YSZ) is widely used as a top coat in Thermal Barrier Coatings (TBCs) to protect metallic substrates. These coatings are exposed to severe high strain rate fields along their life, for example during the impact of debris...

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...

Machining of long ceramic fibre reinforced metal matrix composites – How could temperature influence the cutting mechanisms? (2023)
Journal Article

Metal matrix composites (MMCs) offer a unique set of properties due to the ductile-brittle combination produced by the matrix and the reinforcements. Conventional MMCs are usually particle-reinforced, and their cutting mechanisms have been thoroughly...
