is referred as ELTA alloy in abridged notation. It can be used for adding low-content titanium into aluminum alloy, in place of common Al-Ti master alloy[7]. Its chemical compositions are listed... addition, the resultant ZL108 alloy is referred as the electrolytic low titanium alloying ZL108, or in abridged notation of ZL108 (ETA). If the common Al-Ti master alloy is used for fusion alloying......
elongation. The investigation results of KAIBYSHEV et al [10] suggested that a thermomechanically modified 5083 aluminum alloy exhibits enhanced superplastic behavior in the temperature range of 500-570 °C. BAE and GHOSH [11,12] experimentally investigated cavity growth in a superplastic flow of Al-Mg alloy and suggested an improved plasticity-based model. PATANKAR and JEN [13] investigated the effect......
