Subgrain-resolved Analysis of Degradation in Cu Metallization via Scanning 3DXRD and Thermomechanical Modeling
Nikhil Prabhu, Laura Neumann, Michael Reisinger +7
Metallization layers play a key role in the performance and reliability of modern power semiconductor devices. During short-circuit events, rapid heating of power metallization lay…
Unravelling the mechanisms underlying crack initiation in additively manufactured steel
KenHee Ryou, Yaozhong Zhang, James A. D. Ball +7
Metal additive manufacturing (AM) is increasingly adopted for safety-critical applications across the biomedical, aerospace, and energy sectors. However, many AM alloys exhibit sub…
Revealing 3D orientation and strain heterogeneity in calcite generated by bio-cementation
Marilyn Sarkis, James A. D. Ball, Michela La Bella +5
Bio-cementation uses bacterially induced calcite to bind sand grains, offering a low-carbon approach to soil stabilization. However, the 3D morphology, orientation texture, and int…
Revealing 3D Strain and Carbide Architectures in Additively Manufactured Ni Superalloys
James A. D. Ball, David M. Collins, Yuanbo T. Tang +4
Fast directional solidification during Laser Additive Manufacturing (LAM) produces a complex microstructure in nickel-based superalloys, comprising columnar grains with cellular su…
