Abstract

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 hot rolled MC-TRC sample showed excellent tensile strength and ductility compared to the other samples. Detail microstructural studies revealed that fine grain structure can be obtained by giving maximum deformation during the hot rolling process and finer the grain size better is the tensile properties at warm forming temperature.
