Abstract : The patent application concerns a magnesium-boron composite and is made by mechanically mixing magnesium powder with boron powders. A small amount of lithium may be added to the composite to make the composite more ductile. The mixed powders are then cold pressed, hot pressed, sintered, extruded, rolled, and finally re-extruded. The new product of the unique method will overcome the aforementioned problems. The unique method of making the completely new alloy includes layering of the mixture before extruding which results in a composite alloy with a specific stiffness of about one and one-half times of any other known alloy.
