Materials Map under construction

The Materials Map is still under development. In its current state, it is only based on one single data source and, thus, incomplete and contains duplicates. We are working on incorporating new open data sources like ORCID to improve the quality and the timeliness of our data. We will update Materials Map as soon as possible and kindly ask for your patience.

Giant segregation transition as origin of liquid metal embrittlement in the Fe-Zn system

Abstract

A giant Zn segregation transition is revealed using CALPHAD-integrated density-based modelling of Zn segregation into Fe grain boundaries (GBs). The results show that above a threshold of only a few atomic percent Zn in the alloy, a substantial amount of up to 60 at.% Zn can segregate to the GB. We also found that the amount of segregation significantly increases with decreasing temperature, while the required Zn content in the alloy for triggering the segregation transition decreases. Direct evidence of this Zn segregation transition is obtained using high-resolution scanning transmission electron microscopy. We trace the origin of the segregation transition and its temperature dependence back to the low cohesive energy of Zn and a miscibility gap in Fe-Zn GB, arising from the magnetic ordering effect, which is demonstrated by ab initio calculations. We show that the massive Zn segregation resulting from the segregation transition greatly assists with liquid wetting and reduces the work of separation along the GB. These findings reveal the fundamental origin of GB weakening and therefore liquid metal embrittlement in the Fe-Zn system.
