Hardness, Microstructure and Strain Distributions in Commercial Purity Aluminum Processed by Multi Directional Forging (MDF) [PDF]

Materials Research, 2020
Severe plastic deformation (SPD) of metals leads to their strengthening and grain refinement, but to low uniform elongations. Low Strain Amplitude Multi Directional Forging (LSA-MDF) is an important method for increasing this low uniform elongation.

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.
