Abstract
In this paper, a fine distinction between the role of strain-paths on the evolution of mechanical properties has been reported. Commercially pure (CP) titanium plates were subjected to hot rolling of 90% reduction in thickness through different strain-paths such as unidirectional rolling (UDR), multistep cross-rolling (MSCR) and reverse-rolling (RR). It was observed that the sample rolled through RR had higher mechanical properties (both yield strength and ductility) followed by the samples rolled through MSCR and UDR respectively. It was further observed that the RR sample had higher stored energy followed by MSCR and UDR samples which eventually controls the evolution of microstructure and hence defines the mechanical properties.
