The microstructural evolution of interstitial-free (IF) steel subjected to Φ = 90° Equal Channel Angular Extrusion (ECAE) for up to 4 passes via routes A, BA, C and up to 8 passes via routes BC was studied using Electron Back-Scatter Diffraction (EBSD). Routes BC and BA recorded the smallest grain size and aspect ratios and the largest average misorientation and area fraction of high-angle grai...

Equal channel angular rolling (ECAR) process is one of the severe plastic deformation (SPD) methods that have been used to make ultra-fine grain (UFG) materials with improving the mechanical properties of samples. After performing the process at several paths, a large strain is applied to the material that can cause decreasing the grain size and improving the mechanical and physical properties ...

equal channel angular rolling (ecar) process is one of the methods that have been used to makeultra-fine materials by imposing severe plastic deformation. after repeating the process severaltimes, a large effective strain is applied to the sample that can cause decreasing the grain size andimproving the mechanical and physical properties of the metal. in this study, thermal conductivityof the s...
