Analytical and Experimental Investigations on Influential Parameters of Superplastic Forming of Titanium Based Workpieces

Cavitation During Superplastic Forming

Cavitation is the opening of pores during superplastic forming, typically at grain boundary triple points or on second phase grain boundary particles during slip of grain boundaries. Theories for the initiation of cavitation are reviewed. It seems that cavitation is unlikely to occur by processes intrinsic to metals such as dislocation mechanisms or point defect condensation. It is proposed tha...

Optimization of Superplastic Forming Technology

The objective of this paper is a superplastic forming (SPF) technologies design and optimization. The conditions of superplasticity are very sensitive to strain rates and temperature characteristic of deformation process. The presented work gives an approach to design the SPF technologies that satisfies such conditions.A possibility to decrease the temperature of the industrial forming of the T...

Numerical analysis and design of industrial superplastic forming

In the aerospace industry, the production of structural shell components with a prescribed thickness distribution by superplastic forming requires the specification of the initial thickness profile in the undeformed sheet. To this purpose, a finite element simulation methodology developed previously for the analysis of superplastic deformation processes along with the optimum monitoring of the ...
