Abstract
Herein we report on the effect of the reinforcement volume fraction on the mechanical properties of a novel nanocrystalline magnesium, Mg, matrix composite reinforced with Ti2AlC. Increasing the volume fraction of the reinforcement reduced the average size of Mg nanograins. Both Mg and Ti2AlC have been classified as kinking nonlinear elastic (KNE) solids. KNE solids trace fully reversible, reproducible, hysteretic stress-strain loops that can be characterized by three independent parameters: stress,, nonlinear strain, epsilon NL, and energy dissipated per cycle per unit volume, Wd. all of which can be obtained from the stress-strain loops. The results are in excellent agreement with our incipient kink band (IKB) based model. The Mg nanograins are also extraordinarily thermally stable; heating the composite three times to temperatures 50 degree C above the melting point of Mg did not lead to coarsening of the nanograins.
