Processing Commercial Aluminum Alloys for High Strain Rate Superplasticity

Abstract

The superplastic forming of sheets, although used on a small, specialized scale, has not yet been adapted for high-volume purposes. In processing for superplastic properties, the key microstructural features are grain size and grain-boundary misorientation. Current research trends are two-fold: to evaluate bulk processing of ultrafine-grained materials, and to understand the superplastic behavior of ultrafine-grained materials. Work is continuing on understanding the relationship between grain size and superplastic strain rate and superplastic temperatures. In this paper, strategies are reviewed for producing microstructures with enhanced superplastic characteristics.
