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]

open access: yesMaterials 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.

Microstructure Evolution of AZ80 Magnesium Alloy during Multi-Directional Forging Process

open access: yesMATERIALS TRANSACTIONS, 2014
Grain refinement of a magnesium alloy, AZ80, was studied in multi-directional forging (MDF) with decreasing temperatures from 683 to 573K. The MDF was carried out up to accumulative true strains of around 7 with changing the loading direction from pass to pass.
