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 کاملAchieving microstructures prone to superplastic deformation in an Al - Zn - Mg - Cu alloy by equal channel angular pressing
An Al-Zn-Mg-Cu alloy without Sc or Zr additions was subjected to overaging and processing by equal channel angular pressing, obtaining a grain size of ∼160 nm and a fraction of high-angle boundaries of 56%. The high elongations attained at high strain rate (10-10 s) and low test temperature (250-300 oC) are attributed to the formation of new recrystallized grains, ∼500 nm in size, during heatin...
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...
متن کاملMicrostructure and its Relationship to Mechanical Properties in Equal Channel Angular Rolled Al6061 Alloy Sheets
Equal channel angular rolling (ECAR) is a severe plastic deformation (SPD) technique which has been used to produce metal sheets with ultra-fine grain structure. In the present work, the relationships between the mechanical properties and microstructure of samples during the ECAR process have been investigated. The Rietveld method was applied to analyze the X-ray diffraction pattern and to det...
