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

Microstructural simulation of dynamic recrystallization [PDF]
Acta Metallurgica et Materialia, 1992 A Monte Carlo model for dynamic recrystallization has been developed from earlier models used to simulate static recrystallization and grain growth. The model simulates dynamic recrystallization by adding recrystallization nuclei and stored energy continuously with time.

Influence of choked angle of bearing channel on profile grain structure during multi-hole extrusion of aluminum alloy [PDF]
, 2018 Direct extrusion of aluminum alloy EN AW-6060 was carried out applying a four-hole die with pair-wise parallel and choked long channels. Due to the dissimilar friction inside parallel and choked channels profiles with different length were extruded ...
