A dimensionless weigh mathematicmodel for the criteria of superplastic air bulge forming was developed to be: Q_w=1.56WS/HF+2.37(θ-φ)π/180-r/r_0+0.19The superior formability of components is approaching if Q_W≥1, and the worse, if Q_W<1. Itwas confirmed by practice that the above mentioned model is with more accuracy.
