The present conference on emerging applications of superplastically formable materials discusses the superplastic deformation mechanisms of aluminum alloys, microstructural evolution in a P/M 7xxx Al alloy, fine-grained superplasticity at 300 C in a wrought Al-Mg alloy, and the extended ductility of Al and alpha-Fe alloys through dynamic recovery mechanisms. Also discussed are models for superplastic forming under axisymmetric and plane-strain conditions, cavitation failure in superplastic alloys, the effects of void formation on superplastic 7475 Al alloy mechanical properties, superplasticity in SiC whisker-reinforced Al alloys and mechanically-alloyed Al aerospace alloys, the effect of microstructure on Al-Li-X alloys' superplastic behavior, and hollow Ti-alloy turbofan blades' superplastic forming.
