  • Superplasticity of the 5083 aluminium alloy with the addition of scandium = Superplastičnost aluminijeve zlitine 5083 z dodatkom skandija
    Smolej, Anton, 1941- ; Skaza, Branko ; Slaček, Edvard, 1951-
    This paper deals with the superplastic properties of an Al-4Mg-0.6Mn alloy (AA5083) with the mass fraction of scandium 0.3 %. The investigated alloy was produced by ingot casting and ... thermomechanically treated with hot and cold rolling into sheet with a thickness of 1.4 mm. The superplastic properties of the alloy were investigated with tensile tests at strain rates in the range 3 x 10[sup]{-4} s[sup]{-1} to 1 x 10[sup]{-2} s[sup]{-1} and at temperature from 470 °C to 570 °C. The true-stress, true-strain characteristics, the elongation to failure, the strain-rate sensitivity index and the microstructure of the alloy were determined. The elongation to failure increased with the test temperature and was over 1400 % at an initial strain rate 7.5 x 10[sup]{-4} s[sup]{-1} and a temperature of 550 °C.
