OPTIMIZATION OF REGIMES OF THERMODEFORMATION TREATMENT OF HIGH-STRENGTH ALUMINUM ALLOY 019705

摘要

The effect of regimes of thermodeformation treatment of high-strength aluminum alloy 019705 developed at the department of physical metallurgy of nonferrous metals of NITU "MISiS" is studied. The modes of fabrication of semiproducts are optimized using a "Gleeble System 380" (Hydrawedge II) facility for physical simulation of thermomechanical processes at deformation rates 0.01-10 sec~(-1) in a temperature range of 200 - 450℃. The scheme of fabrication of deformed semiproducts (pressing, rolling) and the rates and temperatures of the deformation are shown to be interrelated.
