COMPLEX INFLUENCE OF MODES OF PRESSING AND SUBSEQUENT HEAT TREATMENT ON MECHANICAL CHARACTERISTICS OF STRUCTURES FROM AN ALLOY OF SYSTEM Al-Mg-Si

摘要

Complex influence on mechanical properties of extruded shapes of alloy 606020 (system Al-Mg-Si) of following factors are investigated: temperature of the shape at the press exit, type of aging and duration of artificial aging, as well as time from the extrusion to testing. Experiments were carried out on the of extrusion line equipment of joint-stock venture "Yugchermet" with the horizontal direct press of 13,5 MN force.
