Notes:
The Kocks-Mecking method of analysis is applied to solid solutions of up to 2.6 at.% Znto separate the contributions to the alloys’ strain hardening rate from dislocations storage, solute insolution, and twinning, for temperatures between -50 ºC (273 K) and 200 ºC (473 K). Athermalstorage of dislocations seems to account for the largest share of the strain hardening rate for both thepure metal and the solid solutions at or below room temperature. Solute in solution does notincrease the strain hardening rate over that of pure Mg, although it delays the onset of dynamicrecovery, especially for the higher alloys, presumably due to short range order. Twinning remains avery important deformation mechanism for the pure metal and the dilute alloys up to 200 ºC
