Synergistic enhancement of strength and toughness of β-Ti alloy with a fine grain: Effect of deformation temperature [PDF]

MATEC Web of Conferences
It 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

Microstructural evolution and enhanced properties by multi-directional forging of 6201 aluminum alloy

Matéria (Rio de Janeiro)
Abstract In this work, the microstructure evolution and mechanical properties of 6201 aluminum alloy during multi-directional forging (MDF) and solution-aging were systematically studied. In the MDF process, the deformation of 6201 aluminum alloy was not uniform, and the increase of forging passes can effectively improve the inhomogeneity.
