Phenomenology of quality criteria material forgings from aluminum-magnesium alloys AMg group

From the standpoint of technological heredity, the phenomenology of assessing the quality of the forging material from aluminum alloys of the AMg group in terms of the dependence of their tightness and corrosion resistance on the parameters of the thermal treatment of the ingot and on the prevailing mechanisms of its plastic deformation is considered. Based on the metallic features of alloys, and using a phenomenological approach, in the form of graphs and approximating formulas, the numerical dependencies of experimentally established hardness indicators, loosening of the forging material, and the volume content of excess phases in it, on the amount of deformation accumulated by the material, on its modes are determined. Numerical data for calculations were obtained by mathematical modeling of hot plastic deformation processes using the software product Q-Form. Joint assessment of loosening and volumetric content of excess phases is substantiated in the form of complex quality index of forging material from aluminium alloys of AMg group, and technological solutions are numerically substantiated to obtain their value not exceeding the specified value.
