INFLUENCE OF THE PRIMARY SOLIDIFICATION ON THE SECONDARY SOLIDIFICATION DURING SEMISOLID METAL (SSM) PROCESSING OF A356.0 ALUMINUM ALLOY BY MECHANICAL STIRRING

  Abstract:   The aims of this research were to investigate the effects of semisolid metal (SSM) processing parameters (i.e., shear rates –times – temperatures combinations) on the primary solidification products and isothermal holding duration, subsequent to cessation of stirring on the secondary solidification of Al-Si (A356) alloy.   The dendrite fragmentation was found to be the governing m...

Experimental and Numerical Investigation on the Heat Treatment Effects of AA6063 Aluminum Alloy Tubes During Rotary Draw Bending

In this study, the effects of heat treatment of aluminum alloy on the tube bending process were investigated in the rotary draw bending process. As two experimental and numerical simulation methods were used to determine the wall-thinning, ovality, and spring back for extruded, annealed, and aged AA6063 aluminum alloy tubes in different bending angles and bend radii. Numerical simulations were ...
