    Notes: The billet of magnesium AZ31B was made by twin-screw rheo-cast, and the specimencut from the rheo-cast billet and normal cast billet were compressed in Gleeble-3000 hot simulator.The deformation temperature was 300, 350[removed info], and the strain rates were 0.001~1s-1. The relationshipamong flow stress, deformation temperature and strain rates were analyzed. The variation of themicrostructure was observed and compared after the specimen was hot compressed. The resultsshow that the surface of the rheo-cast specimen is much more smooth than the normal castspecimen after the compression. The dynamic recrystallization had taken place during thecompression and the recrystallized grain of rheo-cast sample is more tiny than normal castspecimen

    Microstructure and Mechanical Properties of Rheo-Extruded AZ31 Mg Alloy (2008)

    Notes: A new rheo-extrusion technique has been developed to produce extruded profiles. TheAZ31 slurry is fabricated by a twin-screw mechanism, and has spheroidal solid particles with agrain size of about 50 to 80μm. The slurry was introduced into an extrusion container with an innerdiameter of 95mm, and then squeezed to a billet before extruding into a round bar with a diameterof 22mm using a 500kN extrusion machine. It is found that the new technique has a lowerdeformation resistance than that of the conventionally hot extrusion technique in the same extrusionvelocity. The microstructure and mechanical properties of the rheo-extruded bars were examined indetail. The results illustrated that grains of the bar were very fine with the average grain size about2.3μm，and the mechanical properties were improved substantially compared with those of thesame alloy produced by the conventional hot extrusion
