AM is increasingly adopted in modern industries. However, most commercial metal alloys still cannot be reliably printed. We use in-situ synchrotron X-ray diffraction and kinetic modelling to uncover phase evolution dynamics during rapid solidification. Based on the insights, we engineer microstructures and design ultrahigh-performance alloys specifically for AM.

We use in situ neutron diffraction to investigate the structural evolution of AM metallic materials under service-relevant conditions, including heating and mechanical loading. Real-time monitoring of phase transformations and microstructural evolution enables the establishment of processing–structure–property relationships and facilitates microstructure-informed materials design.

Metal matrix composites (MMCs) consist of a metal or alloy matrix reinforced with secondary phases, which gives them superior physical and mechanical properties. These properties are governed by the composite's microstructure. This research aims to elucidate the microstructure formation and deformation mechanisms of additively manufactured MMCs, enabling the fabrication of composites with tailored microstructures and performance.
