An experimental metallographic method for determining strain distribution in a cold formed workpiece is presented in this paper. The method, based on the dependence of recrystallized grain size on prior deformation, was applied to a bulk formed eleme

When divided material flow is enabled during extrusion process, the required forming load is lower compared to a conventional process. The reduction of forming load leads to higher quality of extruded part and longer tool life. One way to achieve div

This paper presents a novel approach for edge detection and concatenation. It applies the proposed method on a set of optical microscopy images of aluminium alloy Al 99.5% (ENAW1050A) samples with different grain size values. The performance of the p
