The deformation behavior of AZ31B magnesium alloy sheet is studied in this paper. In view of its two characteristics, superplasticity and deformation instability, through the superplastic unidirectional tensile (initial strain ratio \( \rho_{0} < 0) \) and bidirectional tensile (bulging, the initial strain ratio \( \rho_{0} > 0) \) test, strain distribution under different deformation paths and strain path changes at the minimum cross section were studied. Besides, the tensile instability process of AZ31B magnesium alloy sheet was analyzed. The forming limit curve of AZ31B magnesium alloy sheet (FLC) was established. According to the curve analysis of the tensile load and the true strain at the minimum cross section of the tensile specimen, the industrial state AZ31B magnesium alloy sheet shows excellent superplasticity at a certain deformation velocity and temperature. When \( d\varepsilon_{2} = 0 \), the AZ31B magnesium alloy sheet was prone to present concentrated instability.
