Abstract
sis is concerned and devoted to study:
The effect of temperature and third element addition on the Zn-Al alloy and studying behavior of both alloys which are Zn-0.5wt. %Al and Zn-0.5wt. % Al-0.3wt. %Cu alloys.
Study of the parameters β, n of the transient creep and m and ε ̇st of the steady state creep at temperature range from 433 to 553K.
Study of the effect of Cu addition on the Zn-0.5wt. %Al alloy at different temperatures and various applied stresses from 15.6Mpa to 23.4Mpa.
Study of the grain boundary refining which results from addition of Cu to the Zn-0.5wt. %Al alloy
