Title:
MAGNESIUM ALLOY AGING TREATMENT MATERIAL, METHOD FOR PRODUCING SAME, OA DEVICE USING SAME, TRANSPORT DEVICE AND COMPONENT THEREOF
Document Type and Number:
WIPO Patent Application WO/2021/111989
Kind Code:
A1
Abstract:
Provided is a highly-versatile magnesium alloy aging treatment material that is capable of providing compatibility between strength and large thermal conductivity in a temperature range that includes room temperature. The magnesium alloy aging treatment material contains 1 mass% or less of Ca and 3 mass% of less of Zn, with the remainder comprising Mg and unavoidable impurities. Precipitates of a Guinier-Preston (GP) zone or the like comprising Mg, Ca and Zn are dispersed on the (0001) surface of a magnesium parent phase. The longitudinal direction of the GP zone on the (0001) surface is from 4.0 to 5.0 nm, and the number density of the GP zone is in the range of 1 × 10 20 to 1 × 10 24m-3.
