Deformation of aluminium alloy AL20 in semisolid state

During semisolid deformation of aluminium alloy AL20, as the deformation strain increases, the deformation stress first increases to reach a peak value, then decreases to a minimum value, after which the stress increases towards the end of the deformation. The deformation stress increases as the deformation rate increases at the beginning of the deformation. The degree of segregation is the highest at the middle deformation temperature.
