Description

The object of study - wrought alloys of 5xxx series and 7xxx alloys, additionally alloyed by Sc, PM and REM. It was improved compositions of wrought aluminum alloys 5xxx and 7xxx series and manufacture of half-stuff of these alloys (melting technology, modes of extrusion in the manufacture of rods and strips, rolling pattern in the manufacture of sheets). It was investigated the effect of alloying, degree of deformation, annealing conditions (5xxx series alloys) and heat treatment (for 7xxx series alloys) on the structure, the mechanical and corrosive properties of the corresponding half-stuffes. With the developed physical and technical principles of production of ingots and half-stuffes, obtained materials in terms of mechanical properties and corrosion resistance superior to those of known conventional aluminum alloys. On the level of fatigue limit values developed alloys have significantly higher values than the standard and experimental alloys contained in the scientific literature.
