A Note on General Study of Mechanical Behavior-Related Atomic Scale Mathematical Model of Al and Mg Alloys

Aluminum and magnesium alloys and metal matrix composites are having high strength-to-weight ratio than many other steels. The atomic model is developed based on 1 atom of aluminum, 1 atom of magnesium, and/or 1 vacancy. These Mg atoms form angles with Al atoms in line. The non-bonding potentials are matched with bonding potentials to arrive at force and an angle. Then critically resolved shear stress for a single grain can be obtained by assembling the defects and generation of dislocations with thermodynamic feasibility. From this, microscopic levels of stress-strain in a phenomenological model can be developed to determine mechanical behavior properties.
