TL;DR: In this article, commercial purity titanium (CP-Ti) grade 2 was hydrostatically extruded (HE) in 20 consecutive passes with cumulative true strain of 5.47 without intermediate annealing.

TL;DR: In this paper, the grain connectivity of ex situ MgB2 is affected by the applied sheath and the mode of deformation, and it was found that the external pressure improves the inter-grain connectivity but decreases the pinning.

TL;DR: In this paper, the thermo-plastic treatment of the CuCrZr alloy was used to achieve a better compromise between its electrical conductivity and hardness, and the material obtained had an ultrafine-grained structure (d2 = 200nm) and a high ultimate tensile strength UTS (UTS) UTS=630 MPa, values which are much higher than those of the reference commercial material used for the fabrication of the spot-welding electrodes.

TL;DR: In this paper, anisotropy of uni-axial deformation behavior of commercially pure (CP) Titanium has been studied for small punch testing of longitudinal and transverse specimens.

TL;DR: In this article, a microstructure-strength relationship for pure titanium (grade 2) fabricated by hydrostatic extrusion, an unconventional severe plastic deformation technique, has been quantified within the present study.
