    <title language="eng">Effect of Extrusion Temperature on the Plastic Deformation of an Mg-Y-Zn Alloy Containing LPSO Phase Using In Situ Neutron Diffraction</title>
    <abstract language="eng">The evolution of the internal strains during in situ tension and compression tests has been&#13;
measured in an MgY2Zn1 alloy containing long-period stacking ordered (LPSO) phase using&#13;
neutron diffraction. The alloy was extruded at two different temperatures to study the influence&#13;
of the microstructure and texture of the magnesium and the LPSO phases on the deformation&#13;
mechanisms. The alloy extruded at 623 K (350 °C) exhibits a strong fiber texture with the basal&#13;
plane parallel to the extrusion direction due to the presence of areas of coarse non-recrystallised&#13;
grains. However, at 723 K (450 °C), the magnesium phase is fully recrystallised with grains&#13;
randomly oriented. On the other hand, at the two extrusion temperatures, the LPSO phase&#13;
orients their basal plane parallel to the extrusion direction. Yield stress is always slightly higher&#13;
in compression than in tension. Independently on the stress sign and the extrusion temperature,&#13;
the beginning of plasticity is controlled by the activation of the basal slip system in the dynamic&#13;
recrystallized grains. Therefore, the elongated fiber-shaped LPSO phase which behaves as the&#13;
reinforcement in a metal matrix composite is responsible for this tension–compression asymmetry.</abstract>
