Re-strengthening in AA6063 Alloy During Equal Channel Angular Pressing
Equal channel angular pressing (ECAP) is carried out using two different configurations for the exit channel of the ECAP die, i.e., relieved and choked, with angles of 0.2 °. It is found that using a die with relieved exit channel, the sample was extruded for 6 passes with no surface cracks and an average cell size of 727 nm and a fraction of high angle grain boundaries of 54 % were achieved. M...
متن کاملHot and Cold Tensile Behavior of Al 6061 Produced by Equal Channel Angular Pressing and Subsequent Cold Rolling
The full annealing AA6061 aluminum alloy was subjected to severe plastic deformationvia the combination of equal channel angular pressing (ECAP) and cold rolling (CR) in order torefine its microstructure and to improve its mechanical properties. According to the results of hotand cold tensile tests, the combination of ECAP and CR significantly affected the final strengthand ductility of studied...
متن کاملCharacteristics of Cavitation in a Superplastic Magnesium Az31 Alloy Processed by Equal- Channel Angular Pressing
Experiments were conducted on a magnesium AZ31 alloy to evaluate the role of cavitation in high temperature superplasticity. Samples were processed by equal-channel angular pressing (ECAP) and then pulled to failure in tension at a temperature of 623K. Similar tests were also conducted on the as-received alloy. The results show the development of significant internal cavitation in this alloy wh...
متن کاملExperimental Investigation of Thermal Conductivity of Aluminum Alloy 3003 Produced by Equal Channel Angular Rolling Process
Equal channel angular rolling (ECAR) process is one of the methods that have been used to make ultra-fine materials by imposing severe plastic deformation. After repeating the process several times, a large effective strain is applied to the sample that can cause decreasing the grain size and improving the mechanical and physical properties of the metal. In this study, thermal conductivity of t...
