Cavitation has been an important consideration in fabricating complex metal parts by superplastic forming processes. The basic processes leading to cavitation failure at working temperatures are nucleation, growth, and coalescence of cavities. The objectives of the project include: (1) the understanding of the deformation behavior of modified 5083 Al alloy through proper evaluation of superplastic deformation mechanisms; (b) the evaluation of the exact mechanism of the cavity nucleation and early growth; (3) predicting the degree of overall cavitation developed during superplastic deformation. |
