• Magnesium alloy sheet containing Mg (in hexagonal closed packed (HCP) crystal structure at room temp) & other alloying elements is a major engineering challenge, limiting its use to cast form and restricting to lightweight structural materials of aerospace & automotive sectors.
• It is evident that, by using Rolling technique to make Mg alloy sheets, one of ductility or strength is compromised while trying to improve the other.
• Also, this technique involve multiples processing stages in manufacturing of magnesium alloy sheet, making process a complicated, time consuming & costly process.
• Hence, the present patent is directed to solve the limitations stated above.

The present patent discloses method (FIG-1) of producing high performance magnesium alloy sheets comprises:

• preparing a Mg alloy ingot (at least one ZK60, AZ31 and WE43 magnesium (Mg) alloys) with engineered initial microstructure with enhanced microstructural conditions;
• heating the Mg alloy ingot in muffle furnace with an inert environment to a predetermined temp (either 250°C or 400°C) ingot for 23-25 minutes;
• subjecting the Mg alloy ingot to a hot rolling process with rolling speed of 12 revolution per minute (rpm) with a thickness reduction between 50% & 70% in a single pass;
• imparting rolling loads ranging between at least one of 57-63 tons and 45-50 tons during the hot rolling process to produce two grades of high performance Mg alloy sheets.
