Ultrafine grain development in copper during multidirectional forging at 195 K
Philosophical Magazine Letters, 2007 Strain-induced evolution of ultrafine grains in pure copper was studied in multidirectional forging (MDF) at 195 K. The stress–strain behaviour was characterized by rapid strain hardening during early processing and the rate of strain hardening gradually decreased with straining, leading to an apparent steady-state flow at large cumulative strains of ...

Microstructural evolution of Mg-7Al-2Sn Mg alloy during multi-directional impact forging
Journal of Magnesium and Alloys, 2015 Multi-directional impact forging (MDIF) was applied to a Mg-7Al-2Sn (wt.%) Mg alloy to investigate its effect on the microstructural evolution. MDIF process exhibited high grain refinement efficiency.

Grain refinement of magnesium alloys by dynamic recrystallization (DRX): A review
Journal of Materials Research and Technology, 2023 For elevated-temperature thermomechanical processing, the occurrence of recrystallization during straining is known as dynamic recrystallization (DRX), which usually happens in Mg alloys during practical hot deformation processes such as rolling, forging,

Ultrafine-grained structure formation in Ti-6Al-4V alloy via warm swaging [PDF]
, 2014 The influence of warm swaging on the structure and properties of Ti-6Al-4V alloy was studied. Warm swaging of the alloy in the interval 680-500°C with the total strain of ε=2.66 was found to be resulted in the formation of a homogeneous globular ...
