Effect of Multidirectional Forging on Microstructure and Properties of AZ40 Alloy [PDF]

Journal of Physics: Conference Series, 2021
Abstract AZ40 alloy was operated with the plastic deformation by multidirectional forging (MDF). The evolution rules of microstructure and texture during forging were analyzed by means of metallographic microscope and electron backscattering diffraction (EBSD), and the evolution mechanism of texture during forging is explored.
