Achieving High-Strength and Toughness in a Mg-Gd-Y Alloy Using Multidirectional Impact Forging. [PDF]
Materials (Basel), 2022 High strength and toughness are achieved in the Mg-4.96Gd-2.44Y-0.43Zr alloy by multidirectional impact forging (MDIF). The forged sample has a fine-grained microstructure with an average grain size of ~5.7 µm and a weak non-basal texture, and it was characterized by an optical microscope (OM), scanning electron microscope (SEM), and electron back ...

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 ...
