Abstract
The transitional effects of temperature on the plastic and superplastic properties of Al 5083 are investigated using simple tensile tests. Thermal variations depicted pronounced effect on the deformation behavior, elongation, cavity growth and modes of failure. Three temperature regimes were identified on the basis of fracture behavior and microstructural characteristics. Plastic behavior was observed at 400.dgree/C and superplastic behavior above 500.degree/C. Plastic localization controlled the failure in the plastic regime but on an increase of temperature above 400.degree/C. The deformations were less localized and more cavities were observed. The results showed that the cavity linkages controlled elongation in the superplastic range.
