Abstract

The invention relates to a quick preparation method of nano magnesium alloy powder. The quick preparation method includes aiming at the circumstance that magnesium alloy powder is difficult in grain refining, adopting a hydrogenation-dehydrogenation method, and preparing to obtain the nano magnesium alloy powder through smashing of magnesium alloy blocks, sifting, hydrogenating, heating, dehydrogenating and vacuum drying. The quick preparation method is advanced in process, simple, convenient and detailed and accurate in data. The prepared magnesium alloy powder is smaller than or equal to 30nm in grain diameter, product purity is high and reaches 99.5%, and the quick preparation method is a quite ideal method for quickly preparing the nano magnesium alloy powder.

Description

technical field [0001] The invention relates to a rapid preparation method of nano-magnesium alloy powder, which belongs to the technical field of preparation and application of non-ferrous metal alloy powder. Background technique [0002] Magnesium alloy is a non-ferrous light metal alloy, which has been widely used in the fields of electronics, automobiles, and aerospace industries. Due to the low strength and poor deformation ability of magnesium alloys, the mechanical properties of magnesium alloys are at a low level; in order to improve It is an effective method to improve the comprehensive properties of magnesium alloys, expand the application range of magnesium alloys, and refine grains. [0003] At present, the grain refinement methods of magnesium alloys include high-energy ball milling, equal channel extrusion, and rapid quenching of melts. Great limitations. Contents of the invention purpose of invention [0004] The purpose of the present invention is to a...
