Grain size and texture changes of magnesium alloy AZ31 during multi-directional forging
Transactions of Nonferrous Metals Society of China, 2008 Grain size and texture changes of magnesium alloy AZ31 were studied in multidirectional forging (MDF) under decreasing temperature conditions. MDF was carried out up to large cumulative strains of 4.8 with changing the loading direction during decrease in temperature from pass to pass.

High Temperature Materials and Processes, 2018 Multi-directional forging (MDF) is one of the most promising severe plastic deformation (SPD) methods used in fabricating large-scale bulk metal materials with ultra-fine grains (UFG). A finite element model for MDF is developed to investigate the strain

Synergistic enhancement of strength and toughness of β-Ti alloy with a fine grain: Effect of deformation temperature [PDF]
MATEC Web of ConferencesIt is difficult for as-cast titanium alloys to achieve high strength and toughness due to the presence of coarse β grains. In this study, multi-directional forging (MDF) was employed to break down the coarse β grains into fine grains and the mechanism of

Microstructure and mechanical properties of AZ61 Mg alloy prepared by multi directional forging
Transactions of Nonferrous Metals Society of China, 2010 Abstract AZ61Mg alloy was multi directionally forged (MDFed) during decreasing temperature condition from 643 K to 483 K at a true strain rate of 3×10−3 s−1 up to cumulative strain of ΣΔe=4.0 at maximum. A pass strain of Δe=0.8 was employed. While average grain size decreased gradually with increasing cumulative strain, the evolution of fine-grained ...
