AZ31 magnesium alloy sheets were fabricated by severe strain rolling

and effects of rolling temperature on microstructure

texture and mechanical properties of the sheets prepared were investigated.The results show that large strain rolling can be used successfully to fabricate AZ31 magnesium alloy sheets in the temperature range of 250

4

00 ℃

while crack occurs with rolled at 200 ℃.The dynamic recrystallization（DRX）grain size and maximum pole density of the sheets rolled in range of 250

400℃ are increased while the mechanical properties are decrease with the rolling temperature increase. The sheet rolled at 250 ℃ exhibits excellent mechanical properties

and the tensile strength

yield strength and elongation of the sheets reach 327.5MPa

213.2MPa and 29.8%

respectively.
