Title:
HIGH-THERMAL CONDUCTIVITY HIGH-STRENGTH MAGNESIUM ALLOY MATERIAL AND PREPARATION METHOD THEREFOR
Document Type and Number:
WIPO Patent Application WO/2020/062874
Kind Code:
A1
Abstract:
The present application discloses a high-thermal conductivity high-strength magnesium alloy material and a preparation method therefor. The magnesium alloy material consists of the following components in percentage by weight: 1.6-1.8 wt% of Zn, 0.4-0.9 wt% of Mn, 0.2-0.7 wt% of Y, and less than 0.2 wt% of impurities, the balance being Mg. Said method comprises ingot casting, homogenizing annealing treatment, pressing molding, and solution treating and ageing. The magnesium alloy material alloy of the present invention has a few alloy components other than magnesium added therein, resulting in low costs; the magnesium alloy material alloy of the present invention, after pressing and heat treatment, has thermal conductivity being 130 W/m.K or more at room temperature, meeting the requirements of engineering materials for thermal conductivity, and has tensile strength being 250 MPa or more, meeting the requirements of mechanical properties of magnesium alloy use.
