METHODS FOR EXTRUDING COARSE-GRAINED, LOW ALUMINUM CONTENT MAGNESIUM ALLOYS - A simplified explanation of the abstract
This abstract first appeared for US patent application 17872766 titled 'METHODS FOR EXTRUDING COARSE-GRAINED, LOW ALUMINUM CONTENT MAGNESIUM ALLOYS
Simplified Explanation
- The patent application describes a method of forming an extruded billet from a coarse-grained magnesium alloy billet. - The coarse-grained magnesium alloy billet has an average grain size of at least 800 μm and a low aluminum content. - The method involves extruding the coarse-grained magnesium alloy billet at temperatures between 300°C and 360°C. - The resulting extruded billet may have a plurality of twins with lenticular morphology. - These twins occupy at least 20% of the total area of the extruded billet.
Original Abstract Submitted
The present disclosure provides a method of forming an extruded billet from a coarse-grained magnesium alloy billet. The method includes extruding the coarse-grained magnesium alloy biller at temperatures greater than or equal to about 300° C. to less than or equal to about 360° C. to from the extruded billet. The coarse-grained magnesium alloy billet has an average grain size greater than or equal to about 800 μm, and has a low aluminum content. The coarse-grained magnesium alloy billet includes greater than or equal to about 0.5 wt. % to less than or equal to about 3 wt. % of aluminum. The extruded billet may have a plurality of twins with lenticular morphology, which occupies an area fraction greater than or equal to about 20% of a total area of the extruded billet.
