| dc.description.abstract | The elevated temperature mechanical characteristics of an aluminum-magnesium-zirconium alloy were studied. Thermomechanical processing consisted of solution treating and hot working at 440°C and then warm rolling at 300°C to 94% reduction. Subsequent treatments included annealing at 200°C for one hour, and recrystallizing for one minute at 440°C. Tensile testing of warm rolled, annealed, and recrystallized material was conducted at various strain rates and temperatures. The data was analyzed to determine strain-rate sensitivity coefficients and activation energies, in turn to be correlated with microstructural data concurrently obtained on this superplastic alloy. This material exhibits particularly good ambient properties in addition to the superplasticity. | |
