| Abstract | A new wrought magnesium alloy sheet, the Mg-1.8Al-1.8Ca wt.% alloy, with high strength and good ductility has been fabricated by the one-step extrusion and subsequent single-pass large-strain rolling process. The microstructure analysis shows that a large amount of un-dynamically recrystallized (un-DRXed) regions exist in the as-extruded alloy. After the large-strain rolling process, the grain size of the sheet is refined and the microstructure becomes more uniform, as compared with the as-extruded counterpart. The average grain size of Mg-1.8Al-1.8Ca alloy is refined from the similar to 2.42 mu m in the as-extruded state, to be similar to 1.68 mu m and similar to 1.42 mu m, after rolling at 350 degrees C and 300 degrees C, respectively. The wrought Mg-1.8Al-1.8Ca alloy sheet, which was rolled at 300 degrees C by one-pass thickness reduction of similar to 78%, exhibits the highest absolute strengths with yield strength of similar to 298 MPa and ultimate tensile strength of similar to 319 MPa, and the moderate elongation to failure of similar to 6% is also obtained. |
