Change in Properties During Aging of Aluminum Alloys (Zakonomernosit Izmeheniya Svoistv pri Starenii Alyuminievykh Splavov)

Abstract

According to A. A. Bockvar, the type of heat treatment based on the processes of a dissociation of a state of an alloy fixed by hardening, is called annealing or aging. During artificial aging in distinction to natural aging not only are the processes of dissociation of the supersaturated solution accelerated but another structure and a different complex of mechanical and physical properties of the alloys appear. When increasing the duration of the artificial aging or when increasing the aging temperature above the conditions, which lead to maximum hardness there occurs a lowering of the hardness and a creep limit, and elongation increases insignificantly or doesn't change remaining at a comparatively low level.
