Journal of Materials Research and Technology, 2020 Severe Plastic Deformation (SPD) leads to grain refinement and strengthening of metals. Among the many SPD processing methods, Multi-Directional Forging (MDF) is the only one where in-situ material stress–strain curves can be obtained. These are adequate

Microstructural Evolution and Refinement Mechanism of a Beta-Gamma TiAl-Based Alloy during Multidirectional Isothermal Forging. [PDF]
Materials (Basel), 2019 Multidirectional isothermal forging (MDIF) was used on a Ti-44Al-4Nb-1.5Cr-0.5Mo-0.2B (at. %) alloy to obtain a crack-free pancake. The microstructural evolution, such as dynamic recovery and recrystallization behavior, were investigated using electron backscattered diffraction and transmission electron microscopy methods.
