对构成镀锌合金化钢涂层的Fe-Zn系统的五个金属间相中的每一个进行的微柱压缩测试已经揭示，与钢基底直接接触形成的γ相和在最外表面上形成的ζ相是可延展的，取代了其他三个脆性相（γ（1）、δ（1k）和δ（1p））。这些韧性相的压缩变形能力被认为是通过在成形过程中维持脆性相的破裂碎片来减轻涂层失效。(C)2013 Acta Materialia Inc.由爱思唯尔有限公司出版。保留所有权利。
Micropillar compression tests on each of the five intermetallic phases of the Fe-Zn system, which constitute the coating of galvannealed steels, have revealed that the Gamma phase formed in direct contact with the steel substrate and the zeta phase formed on the outermost surface are ductile, sandwiching the other three brittle phases (Gamma(1), delta(1k) and delta(1p)). Compression deformability of these ductile phases is considered to mitigate the coating failure through sustaining ruptured fragments of the brittle phases during the forming process.
