Grain refinement to the sub-micron scale was found enhance both strength and plasticity. In this size range, micro-mechanisms of deformation are not yet sufficiently specified. present work, strain rate sensitivity investigated in an Al-Mg-Si alloy processed by equal-channel angular extrusion. The microstructure controlled conventional transmission electron microscopy orientation imaging-ASTAR....
Ten years of severe plastic deformation (SPD) in Iran, part I: equal channel angular pressing (ECAP)
The superior properties of ultrafine-grained materials fabricated by severe plastic deformation (SPD) have attracted the attention of many researchers around the world. Among the top-ranked countries that are active in this field, Iran is interesting because of the late beginnings of SPD in this country and, subsequently, the highest rate of growth in the number of publications during the last...
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...
