AI Technical Summary

Problems solved by technology

However, these research results have a common shortcoming, that is, the rare earth content in magnesium alloy is relatively high.
The high content of rare earth elements leads to high cost of materials and poor market competitiveness, which limits its application field and scope
Combining these factors, these materials are still in the laboratory stage, difficult to produce in large quantities, and the application of magnesium alloys in structures is limited.

Abstract

The invention relates to a magnesium alloy load-carrying structure plate and a manufacturing method thereof. The load-carrying structure plate comprises a plate body and is characterized in that the plate body is made of a magnesium alloy material, one side surface of the plate body is a plane, upright grooves with mutually connected edges and regular polygon sections are densely distributed on the other side surface of the plate body, the wall thickness of mouths of the upright grooves is in a range from 1mm to 10mm, the inclination of the side walls of the upright grooves is in a range from 2 degrees to 10 degrees, the side length of the mouths of the upright grooves is in a range from 10mm to 200mm, the height of the upright grooves is in a range from 10mm to 50mm, and the thickness of the plate body is in a range from 1mm to 5mm. The manufacturing method utilizes a mould pressing method so as to achieve integrated forming. The magnesium alloy load-carrying structure plate and the manufacturing method thereof have the advantages that the structure is simple, and the whole mechanical property is good.

Description
