Engineering Deformation and Failure in Diamond Triply Periodic Minimal Surface Lattices via 3D Wall‐Thickness Grading

Advanced Engineering Materials, EarlyView.
The work demonstrates that strategic wall‐thickness grading in diamond triply periodic minimal surface lattices enables precise tuning of deformation and failure behavior under compression. Different gradation patterns guide how and where the structure collapses, improving energy absorption or promoting controlled brittle failure.

Modelling the thermal behaviour of Ti6Al4V sintered powder bed in electron beam powder bed fusion (EB-PBF)

Procedia CIRP, 2023
The understanding of thermal behaviour of the sintered powder is a crucial feature in the electron beam powder bed fusion (EB- PBF) process. Accurate analyses may help optimise the process, manage smoke sensitivity materials, and give precious inputs for EB-PBF process modelling and simulation.

An experimental study of residual stress and direction-dependence of fatigue crack growth behaviour in as-built and stress-relieved selective-laser-melted Ti6Al4V [PDF]

, 2019
Selective-laser-melting (SLM) is a powder-bed fusion additive-manufacturing process that has the potential to deliver three-dimensional complex parts with mechanical properties comparable or superior to parts produced via traditional manufacturing using ...

In Situ Neutron Diffraction Study of Strain Evolution and Load Partitioning During Elevated Temperature Tensile Test in HIP-Treated Electron Beam Powder Bed Fusion Manufactured Ti-6Al-4V

JOM
To manufacture almost fully dense components, electron beam powder bed fusion of Ti-6Al-4V is typically combined with post-heat treatment, such as hot isostatic pressing (HIP).

Ti6Al4V‐Bioglass‐Copper Composites for Load‐Bearing Implants

Advanced Healthcare Materials, EarlyView.
We have designed and manufactured a novel Ti64‐based composite by adding 45S5 bioglass (BG) and copper (Cu). Adding BG on titanium improves wear resistance and biocompatibility, whereas Cu addition improves mechanical strength while providing inherent lifelong bacterial resistance.

Adaptive Twisting Metamaterials

Advanced Materials, EarlyView.
This work introduces torque‐controlled twisting metamaterials as a transformative platform for adaptive crashworthiness. By combining multiscale predictive modeling with experimental validation on additively manufactured gyroids, it demonstrates tunable stiffness, collapse stress, and energy absorption.

Characterization of copper & stainless steel interface produced by electron beam powder bed fusion

Materials & Design, 2021
Unalloyed copper (Cu) powder was deposited and melted onto a pre-existing stainless steel substrate using electron beam powder bed fusion (EB-PBF) additive manufacturing (AM) to form dense, bimetallic structures. The AM fabricated Cu was fully dense, and
