High-Temperature Mechanical Behavior of Extruded Mg-Y-Zn Alloy Containing LPSO Phases
Original language description
The high-temperature mechanical behavior of extruded Mg(97-3x)Y(2x)Zn(x) (at. pct) alloys is evaluated from 473 K to 673 K. The microstructure of the extruded alloys is characterized by Long Period Stacking Ordered structure (LPSO) elongated particles within the magnesium matrix. At low temperature and high strain rates, their creep behavior shows a high stress exponent (n = 11) and high activation energy. Alloys behave as a metal matrix composite where the magnesium matrix transfers part of its load tothe LPSO phase. At high-temperature and/or low stresses, creep is controlled by nonbasal dislocation slip. At intermediate and high strain rates at 673 K and at intermediate strain rates between 623 K and 673 K, the extruded alloys show superplastic deformation with elongations to failure higher than 200 pct. Cracking of coarse LPSO second-phase particles and their subsequent distribution in the magnesium matrix take place during superplastic deformation, preventing magnesium grain grow
