Behavior of localized strain under hot compression of cast specimen from Mg–Al–Zn alloy
Axisymmetric hot compression experiments of Mg–Al–Zn specimens in intervals of temperature 250–450 °С and deformation rate (10-3-5)·10–1 s–1 were carried out. Structure formation was studied by optical microscopy. Macroscopically localized strain of cylindrical specimens depending on temperature, strain rates and initial grain size (400 μm and 1400 μm) are investigated. Localized strain diagrams for different initial grain size can be used for development and optimization of hot processing technology parameters are plotting. It is shown that increase of the grain size direct to strain localization increment tendency.
