Constitutive equations for the relationship between stress, strain, strain rate, and temperature are an essential input for modelling thermomechanical processing. Hot plane strain compression testing was used to deform commercial purity aluminium, Al-1Mn, and Al-1Mg alloys at temperatures of 300, 400, and 500°C and equivalent strain rates of 0.25,...
Article
Plane strain compression is a versatile laboratory testing method for simulating industrial hot working operations such as plate and strip rolling. The deformation can be closely controlled to the required conditions of temperature and strain rate, and high strains can be achieved without instability. However, for accurate determination of flow str...

... The presence of metastable Al13(Fe,V)3Si; may be indicative of the very ultrafast cooling rates, (≥10 8 C/s), employed in the present investigation. The β-intermetallic phase with similar lattice parameters: a = b = 0.612 nm, c = 4.15 nm, and β =91 0 , and general composition of Al13(Fe,V)3Si; have been previously linked with a remarkable microstructural resistance that slow down the grain coarsening process [16,17]. The morphologies of intermetallic particles in the samples as extruded at 370 0 C, 400 0 C, 430 0 C, and 460 0 C are shown in Fig. 2b. ...
