Özet
In this research, uniaxial tensile deformation behavior of 5754-O type aluminum-magnesium (Al- Mg) alloy sheets which are used widely in diverse applications ranging from automotive bodies to food processing due to their excellent high strength to weight ratio, corrosion resistance, and weldability were investigated at temperature range between -60 to 250oC and at the range of strain rates 0.0016-0.04 s-1. Mechanical properties such as yield strength (YS), ultimate tensile strength (UTS), strain hardening coefficient (n), strain rate sensitivity (m), total elongation (TE) and reduction of area (RA) were determined. In addition, the elimination of Luder's band (stretcher marks or line) elimination was investigated. The ductility of the alloy was calculated by two different methods. As a result, the ductility was found to increase with increasing temperature and to decrease with increasing strain rate. Luder's band elimination was observed with increasing temperatures and strain rates. The test results at cold temperatures indicated that an increase in total elongation and strain hardening coefficient were observed. Optimum formability condition was obtained at high temperature and low strain rate.
