Abstract

See full text

Provided are a high-strength magnesium alloy profile, a preparation process therefor and the use thereof, wherein same relate to the technical field of the formation of high-strength magnesium alloys. A strengthening phase of the high-strength magnesium alloy profile in an extrusion state mainly comprises LPSO phase and β phase, wherein the volume fraction of LPSO phase is 1-40%; and the volume fraction of β phase is 1-20%. A strengthening phase of the high-strength magnesium alloy profile in an aging state mainly comprises LPSO phase, β phase, β′ phase and γ′ phase, wherein the volume fraction of LPSO phase is 1-40%; the volume fraction of β phase is 1-20%; the number density of β′ phase is 1015-1025 m−3, and the length to thickness ratio l/d thereof is 1:20; and the number density of γ′ phase is 1014-1024 m−3 and the length to thickness ratio l/d thereof is 1:50.
