Microstructure and hardness of bi-modified magnesium AZ31 alloys subjected to severe plastic deformation [PDF]

Journal of Mining and Metallurgy. Section B: Metallurgy
Magnesium alloys are known as attractive materials because of their low density and good thermal conductivity. However, compared to competing metallic materials such as aluminum alloys, magnesium alloys have lower strength.

Microstructure evolution during severe plastic deformation [PDF]

Philosophical Magazine, 2011
Radiotracer diffusion studies of severely deformed, ultra-fine grained materials have revealed the presence of ultra-fast transport paths, which include "non-equilibrium" grain boundaries and free volume. Under some experimental conditions, percolating porosity is produced even in pure copper [Ribbe et al., Phys. Rev. Lett. 2009]. Micro-cracks may form

Deformation mechanisms during severe plastic deformation of a Cu Ag composite [PDF]

Journal of Alloys and Compounds, 2017
A Cu-37 at%Ag composite was produced by high-pressure torsion processing of elemental Cu and Agpowders at room temperature. The initial micrometer-sized powder particles were compressed directlyin the high-pressure torsion tool and subsequently deformed to different strain levels.

Prediction of Generation of High- and Low-Angle Grain Boundaries (HAGB and LAGB) During Severe Plastic Deformation

Metallurgical and Materials Transactions. A, 2020
It is well known that a balance between the generation of low-angle and high-angle grain boundaries (LABG and HAGB) is achieved in materials undergoing a severe plastic deformation (SPD) process.
