A Cyclic Forward-Backward Extrusion Process for Production of Nano-grains Materials
A cyclic forward-backward extrusion (CFBE) process was presented as a severe plastic deformation (SPD) technique to produce nano-grained aluminum rods. According to transmission electron microscopy (TEM) and electron backscatter diffraction (EBSD) results, the average grain size was reduced from 120µm to about 100 nm after four cycles of CFBE. Yield strength and tensile strength of the specimens increased after four CFBE cycles. Compared to conventional SPD techniques, the structure produced by CFBE was more homogenous, containing nearly equiaxed grains.
