Texture Evolution of AZ31 Magnesium Alloy Sheet at High Strain Rates [PDF]

open access: yes, 2010
In the current contribution the mechanical behaviour at high strain rates of AZ31 magnesium alloy sheet is studied. Uniaxial deformation properties were studied by means of tensile split Hopkinson pressure bar (SHPB) at different temperatures.

Investigation of Dynamic Recrystallization of NiTi Shape Memory Alloy Subjected to Local Canning Compression

open access: yesMetals, 2017
Physical mechanism for dynamic recrystallization of NiTi shape memory alloy subjected to local canning compression at various temperatures, 600, 700 and 800 °C, was investigated via electron backscattered diffraction experiments and transmission electron

Dynamic recrystallization of spheroidal graphite iron during hot cutting operations. [PDF]

open access: yes, 2015
The objective of the present paper is to analyse the dynamic recrystallization process occurring during the hot cutting of spheroidal graphite iron. In the first instance, hot cutting tests are performed with an orthogonal cutting test bench.

Investigation on the microstructure evolution and dynamic recrystallization mechanisms of TiAl alloy at elevated temperature

open access: yes, 2021
The flow stress–strain curves appear to be sensitive to deformation conditions. The ratio of critical strain to peak strain ec/ep follows a linear relationship except when the temperature is 1240 °C and the strain rate is 0.001 s−1.

Influence of dynamic recrystallization on texture formation in ECAP deformed nickel [PDF]

open access: yes, 2022
S.575-5803N nickel has been deformed by equal channel angular pressing (ECAP) at 400°C up to 3 passes using route A. The texture with respect to position in the deformed billet, i.e.

Dynamic Recrystallization of a Quartz Porphyroclast [PDF]

open access: yesTexture, Stress, and Microstructure, 1991
Dynamic recrystallization occurs to minimize strain energy via either grain boundary migration or subgrain rotation1,2. Both result in similar microstructures, but whereas in the former new grains have their crystallographic orientation controlled by neighbouring grains, in the latter new grains are derived from the parent grain.

Deformation-activated recrystallization twin: New twinning path in pure aluminum enabled by cryogenic and rapid compression

open access: yesiScience, 2022
Summary: Bulk aluminum rarely forms deformation or annealing twins owing to its high stacking fault energy. We report a novel twinning mechanism mediated by dynamic recrystallization in 6N pure aluminum under high strain rate (∼1.3 × 104 s−1) impact at a

Recrystallization in two-phase alloys [PDF]

open access: yes, 1982
This study is concerned with the effect of particles, which are too small to produce Particle Stimulated Nucleation, on recrystallization. A single crystal model system of internally oxidised copper-aluminium was deformed by rolling.
