Title:
ALUMINUM PLATED STEEL SHEET, THERMOFORMED COMPONENT, AND MANUFACTURING METHODS
Document Type and Number:
WIPO Patent Application WO/2022/161049
Kind Code:
A1
Abstract:
Disclosed in the present invention is an aluminum plated steel sheet, comprising a substrate and a plating layer on the surface of the substrate. The microstructure of the plating layer comprises a Mg2Si phase and an AlMgSiFe phase; and an average crystal grain diameter of the Mg2Si phase is 0.001-5 μm. The present invention can mitigate the problem of melting-induced roller sticking and the problem of a hydrogen embrittlement risk in a thermoforming process of the aluminum plated steel sheet. The present invention further provides a manufacturing method for the aluminum plated steel sheet, and a thermoformed component and a manufacturing method therefor.
