Superplasticity in 2219 aluminum alloy was achieved through thermomechanical processing. Tension tests showed that the alloy exhibits superplastic behavior in the temperature range of 450-540degreesC and strain rates ranging from 2.2x10(-5) to 1.1x10(-1) s(-1). A maximum elongation-to-failure of 670% was recorded at 500degreesC and at the initial strain rate of 2.2x10(-4) s(-1). High cavitation level and intensive grain growth were observed. Sheet of the 2219 aluminum alloy was blow formed into conical shape using two different methods: simple negative and backpressure forming. A strain of 2.1 was obtained at 500degreesC under the backpressure blow fort-ning condition. It was found that elongation to failure under blow forming with backpressure is about 1.5 times higher than that under a simple female forming. Microstructural evolution of blow formed parts was also examined.
