Experimental Studies and Modelling Analysis of Commercial Purity Iron Processed by Asymmetric Rolling
Asymmetric rolling (ASR) is one of the severe plastic deformation (SPD) processes which are prominently used to reduce grain size and refine grain structure of the metals and alloys of commercial interest. In this work, commercial purity iron processed by asymmetric rolling was experimentally studied by means of optical microscopy and transmission electron microscopy (TEM). Tensile tests were performed on the samples under different treatment conditions and the experimental results were compared with the output from the modelling analysis. Modelling results of the mechanical properties of this type of material are in accordance with the grain refinement mechanism.
