Abstract (en)

Disclosed are: a zinc alloy plated steel sheet comprising a base steel sheet and a zinc alloy plated layer; and a method for manufacturing the same, the zinc alloy plated layer comprising a Zn single phase structure as a microstructure, and a Zn-Al-Mg-based intermetallic compound, wherein (0001) preferred orientation degree (f) of the Zn single phase structure, represented by the following relation formula 1, is 50% or higher. [Relation formula 1] f(%)=(I basal /I total ) × 100 (wherein, I total is defined as a value obtained by integrating diffraction peaks of all Zn single phases when an X-ray diffraction pattern is measured to 2 theta 10°-100° by using a Cu-K± source, and I basal is defined as a value obtained by integrating diffraction peaks of Zn single phases related to a basal plane.)
