Abstract

A quantitative method is reviewed for predicting mechanical properties of magnesium alloys and aluminium alloys. This method is constructed on the basis of molecular orbital calculations of electronic structures. A new parameter, Mk, which is the s-orbital energy level for alloying element in magnesium or aluminium, is introduced and used for the prediction. With this single parameter, the yield strength, the tensile strength and the Vickers hardness are predictable even for commercially available alloys with multiple components.
