Discovery of a Zn-Al-Fe quasicrystal-related phase in the zinc coating of hot-dip galvanized CMnSi TRIP steel
Source abstract
Abstract
A Zn-Al-Fe quasicrystal-related phase was identified for the first time in the zinc coating of hot-dip galvanized CMnSi TRIP steel. Transmission electron microscopy (TEM) and selected-area electron diffraction (SAED) revealed characteristic 5-fold and 2-fold symmetries and τ-related diffraction-ring scaling, while energy-dispersive spectroscopy (EDS) indicated an approximate composition of Zn66Al23Fe11 (at.%). The phase was observed both in the Zn coating and near the Fe/Zn interface, suggesting formation through localized interfacial reactions and rapid non-equilibrium solidification during galvanizing.
