title = "Microstructure and plastic deformation behavior of modified AA7075-t6 aluminum alloy",
abstract = "This study investigated the plastic deformation behavior and microstructure evolution of the modified AA7075 alloy (using Eco-Mg in lieu of Mg element). Before the compression tests, the microstructure was observed and phase analysis was performed. As the conditions for the compression tests, temperature range was from 523K to 723K and strain rates were controlled from 10-2 s-1 to 10 s-1 using Gleeble equipment. The flow stress of the modified AA7075 alloy with their small grain size and second phases were slightly higher than that of conventional AA7075 alloy. The activation energy for the plastic deformation of this alloy was about 135.9kJ/mol, a relatively lower value compared with the conventional AA7075 alloy (more than 140kJ/mol). The processing map of the modified AA7075-T6 alloy was plotted and compared with that of conventional alloys. This alloy showed similar formability with the conventional AA7075 alloy, i.e., similar area of stable deformation region. We also attempted to discuss plastic deformation behavior related to its microstructure.",
