Impact toughness and deformation modes of Ti–6Al–4V alloy with different microstructures
TL;DR: The impact toughness and deformation modes of Ti-6Al-4V alloy with different microstructures, i.e., equiaxed microstructure (EM), bimodal microstructures (BM), fine lamellar micro structure (LM1) and coarse lmmar micro structure (LM2), were studied and revealed in detail as discussed by the authors.

On the possibility to reduce ECAP deformation temperature in magnesium: Deformation behaviour, dynamic recrystallization and mechanical properties
Prakash C. Gautam,Somjeet Biswas +1 more
TL;DR: In this paper, the effect of temperature on the dynamic recrystallization (DRX) behavior and its consequence on the microstructure, texture, and mechanical properties in pure magnesium during equal channel angular pressing (ECAP) by route-A up to eight passes ( e E f f = 9.3 ) was investigated.

Twinning characteristics in rolled AZ31B magnesium alloy under three stress states
TL;DR: In this article, a rolled AZ31B magnesium alloy was studied under three different stress states: tension along the normal direction (NDT), compression along the rolled direction (RDC), and torsion about the normal directions (NDTOR) using companion specimens interrupted at incremental strain levels.

Plastic anisotropy and the role of non-basal slip in magnesium alloy AZ31B
Sean R. Agnew,Ozgur Duygulu +1 more
TL;DR: In this paper, a combination of experimental and simulation techniques were used to investigate the plastic behavior of wrought magnesium alloy and found that an increased activity of non-basal dislocations provides a self-consistent explanation for the observed changes in the anisotropy with increasing temperature.
