Tensile behavior of an austenitic stainless steel subjected to multidirectional forging

IOP Conference Series: Materials Science and Engineering, 2014
The mechanical behavior of a chromium -nickel austenitic stainless steel with submicrocrystalline structures produced by multidirectional forging (MDF) to a total strain of ∼ 4 at temperatures of 700 and 600° C was studied. This processing resulted in the formation of uniform ultrafine grained structure with an average crystallite size of 360 and 300 ...

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 ...

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,
