Room temperature tensile anisotropy of extruded magnesium plates

The room temperature tensile behavior of four extruded magnesium plates: AZ31, AM50, ZM21, and AZ61 were evaluated at 0, 45, and 90 degrees to the extrusion direction. The low aluminum content alloys ZM21 and AZ31 exhibited significant anisotropy of ductility and flow strength. The 45 degree to the rolling direction showed the lowest yield strength and a ductility of over 25%. The higher aluminum content materials, AM50 and AZ61 exhibited no …
