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.

Grain refinement in a Cu–Cr–Zr alloy during multidirectional forging [PDF]
Materials Science and Engineering: A, 2014 Abstract Structural changes during plastic deformation were studied in a Cu–0.3%Cr–0.5%Zr alloy subjected to multidirectional forging up to a total strain of 4 at the temperatures of 300 K and 673 K. The deformation behavior was characterized by a rapid increase in the flow stress at an early deformation followed by a steady-state flow at large ...
