Dynamic recrystallization of pure zinc during high strain-rate compression at ambient temperature

, 2020
Due to limited slip systems, forming of Zn-based alloys is typically conducted at elevated temperatures which consumes energy and may degrade mechanical properties.

Dynamic Recrystallization of a Quartz Porphyroclast [PDF]

Texture, 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.

Texture Evolution of AZ31 Magnesium Alloy Sheet at High Strain Rates

, 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.

Solid‐State Diffusion and Intermetallic Phase Formation in Roll‐Bonded Mg–Zn Composites With Kirigami‐Patterned Inlay

Advanced Engineering Materials, EarlyView.
Mg–Zn composites with a thickness of 0.21 mm were fabricated using roll bonding of a kirigami‐patterned Mg alloy inlay within a Zn matrix. Thermal activation following this process led to the formation of tailored intermetallic structures, which provided the composite with enhanced flexural strength.
