A review on effect of multi-directional forging/multi-axial forging on mechanical and microstructural properties of aluminum alloy

The current paper shows the various characteristic features of aluminum and its alloys that have an extensive use in material science and manufacturing processes. These aluminum based alloys possess numerous applications due to their mechanical and interfacial properties which include strength-toweight ratio, fatigue, hardness, density, equivalent strain, and toughness. The adequate process of obtaining fine equiaxed grains in aluminum alloys is Multi-axial forging (MAF) or Multi-directional forging (MDF). This is one among the various severe plastic deformation (SPD) processes that is used to bring about grain refinement. In Multi-directional forging, each sample is initially forged in one direction and then it is rotated by 90 degrees and forged in that direction, this constitutes a pass. Alternate forging of these alloys takes place in order to achieve bulk grain refinement. This paper carefully attempts to grab the attention of the viewer to Multi-directional forging technique and to bring about a review on the present findings and a research on the ongoing aspects of Multi-directional forging.
