Effect of Surface Treatment of Multi-Directionally Forged (MDF) Titanium Implant on Bone Response

Metals, 2019
Multi-directional forging (MDFing) of titanium drastically improved its mechanical properties due to the evolution of an ultrafine-grained structure. Forging strain was repeatedly applied while changing the forging axis during MDFing.

The Control of Flow Localization in the Post Severe Plastic Deformation (SPD) Forming of Aluminum Through the Application of Low Strain Amplitude Multidirectional (LSA-MDF) Forging [PDF]

Materials Research
Severe Plastic Deformation (SPD) of metals leads to their strengthening and losses in the work hardening capacity. The latter causes flow localization upon subsequent forming of the material.

Reasonable utilization of {10-12} twin for optimizing microstructure and improving mechanical property in a Mg-Gd-Y alloy

Materials & Design, 2020
During the deformation of Mg alloys, {10-12} extension twin, as one of the most active deformation mechanisms, contributed much to the formation of basal texture, yet little to dynamic recrystallization (DRX) grains, i.e., effective grain refinement.
