Creep-resistant, High-strength Zn-al and Zn-al-mg Alloys.
U S Pat 3 764 402 1973 Oct; :
Zinc alloys containing 25-40 al and 0-0.7 pct mg have useful mechanical properties after homogenization above the eutectoid temperature and within the miscibility gap, quenched, and then formed at 225 deg.-325 Deg. C. If the forming temperature is below the eutectoid, the alloy is superplastic, andthe forces required for deformation are minimized. If the forming temperature is in the miscibility gap range, deformation forces increase sharply, but the creep resistance is greatly improved. In the latter case, mg additions also increase creep resistance.
