Abstract

Magnesium alloy is the lightest metal structure material for application at present

which has a good application prospect in the lightweight aspect of aerospace.The aerospace application parts are gradually developed towards precision

thin-walled and integrated aspects with the application techniques and requirements increase.Compared with traditional magnesium casting techologies

the process characteristics of investment casting technology have unique advantages for the production of precision and complex thin-walled parts.The application of investment casting in magnesium alloy can better meet the requirements of aerospace parts.The forming technology of magnesium alloy was introduced

and the investment casting for the Mg alloy was emphatically summarized.The existing issue of metal-mold interface reaction and research status were reviewed.
