Giant segregation transition as origin of liquid metal embrittlement in the Fe-Zn system
Reza Darvishi Kamachali, Theophilus Wallis, Yuki Ikeda +5
A giant Zn segregation transition is revealed using CALPHAD-integrated density-based modelling of segregation into Fe grain boundaries (GBs). The results show that above a threshol…
Atomic motifs govern the decoration of grain boundaries by interstitial solutes
Xuyang Zhou, Ali Ahmadian, Baptiste Gault +4
Grain boundaries, the two-dimensional (2D) defects between differently oriented crystals, control mechanical and transport properties of materials. Our fundamental understanding of…
Aluminum depletion induced by complex co-segregation of carbon and boron in a Σ 5 [3 1 0] bcc-iron grain boundary
Ali Ahmadian, Daniel Scheiber, Xuyang Zhou +4
The local variation of grain boundary atomic structure and chemistry caused by segregation of impurities influences the macroscopic properties of poylcrystalline materials. Here, t…
