The influence of pulsing energy input and high temperature on plasticization of aluminium alloy D16

Earlier by authors at dynamic nonequilibrium processes which are realised at the expense of pulsing load, in materials it is formed it is thin – the band, less dense dissipative the structure connected in volume of a material at various scale levels it is shown. And at pulsing input of energy in a material of different class-rooms (reactor steels, heatproof steel, carbonaceous steels of low and average strength, titanic alloy, maraging steel, armco iron, monocrystal alloy, technical copper, aluminium alloys, nanostructured high-strength titanium) it is possible to provide a wide spectrum of regulating strength and plastic properties of materials, namely: plasticize a material on standard ascending branch of the deformations diagramme; to achieve change of extent of stages of a straining and change strength properties at the set stages of deformation; to realise quasi – superplastic state at room temperature (to gain ideally – plastic behaviour of a material to tens percent of a residual deformation) at the expense of repeated pulsing loads; to realise reserves of mechanical properties of materials at a softening stage, include and a stage of growth of a macrocrack. In the present work the effect of agency of high temperature (773 K) on more essential plasticization of aluminium alloy D16 with again formed is revealed at dynamic nonequilibrium processes dissipative structure in comparison with the structure of an alloy strained at static extension.
