Research Abstract |
A description of dislocation movements during creep has been developed through a detailed TEM observation for the Mg-Al-Ca die-cast alloy. Dislocations are introduced within the primary α grain interior in the die-cast process. The basal segments of dislocations are able to bow out and glide on the basal planes under the influence of a stress, and the jogs follow the basal segments with the help of climb during creep. The Laves phase can decrease the climb velocity of dislocations.
