In the present investigation, strips were produced by melt conditioned twin roll casting (MC-TRC) process. The strips were homogenized at 400C for one hour followed by hot rolling (400C) process. Severe deformation was applied to deform the strip up to 40% by single and two passes. Tensile tests at elevated temperature (200C) were conducted on TRC, MC-TRC, and hot rolled MC-TRC samples. Single pass...
Al–10.2%Si alloy when cast near the liquidus temperature has tremendous potential for producing fine grain structure. However, for casting applications, it requires casting at higher superheating, where this alloy results in large dendritic grain structure. Here, we show that, by applying intensive shearing to the liquid metal prior to casting, dendritic growth can be largely suppressed and fine grain...
