Using AZ61 extruded performs

tensile specimens of AZ61 magnesium alloy were fabricated by close-die hot pressing with varied deformation rate.Effects of grain size and texture during close-die hotpressing process on ambient mechanical properties of the alloy specimens were analyzed by OM

EBSD.The results reveal that intense basic texture can be observed in the extruded performs

and the grain is located at hard orientation

so it is difficult to slide up

taking the high yield strength.Under the condition of the similar primary texture intensity

grain refinement can improve the yield strength and elongation of the alloy specimens

however

deformation rate is limited for improving the microstructure and properties of the alloy specimens.
