Divergent Evolution of Slip Banding in Alloys
Bijun Xie, Hangman Chen, Pengfei Wang +8
Metallic materials under high stress often exhibit deformation localization, manifesting as slip banding. Over seven decades ago, Frank and Read introduced the well-known model of…

Frustrated metastable-to-equilibrium grain boundary structural transition in NbMoTaW due to segregation and chemical complexity
Ian Geiger, Diran Apelian, Xiaoqing Pan +3
Grain boundary structural transitions can lead to significant changes in the properties and performance of materials. In multi-principal element alloys, understanding these transit…
