Surface Review and Letters
This study examined the microstructural, mechanical, and corrosion behaviors of a multidirectional-forged (MDF) Mg–Zn–Ca alloy. The results showed significant grain refinement of the alloy after 5 passes of the MDF process from 378[Formula: see text][Formula: see text]m to 23[Formula: see text][Formula: see text]m.

Grain refinement in a magnesium alloy AZ31 was studied in multi-directional forging (MDF) at a strain rate of 3×10-3s-1 with decreasing temperature from 623K to 423K. The MDF was carried out up to large cumulative strains with changing the loading direction during decreasing temperature from pass to pass.

Ultrafine grain of metals can be obtained through severe plastic deformation techniques. One of the severe plastic deformation techniques is multidirectional forging, in which multiple forging is applied on a workpiece in three orthogonal directions. In this study, the multidirectional forging, with varying die dimensions, each with a single press on ...

Controlling the microstructure and strength of copper submitted to multidirectional forging
Materials Science and TechnologySevere plastic deformation (SPD) techniques have been widely used to enhance strength and promote grain refinement in metals. Multi-Directional Forging (MDF), based on successive compressions with strain path changes, enables tailoring of microstructure and mechanical properties by controlling strain amplitude (Δ ɛ )
