  • Densification of Al-Y2O3 composite powder by equal channel angular pressing 
    Yarra, R.; Venkatachalam, P.; Kumar, S.R.; Ravisankar, B.; Jayasankar, K.; Mukherjee, P.S. (Transactions Of The Indian Institute Of Metals, 63(5), 2010: 813-817)
    In this study, equal channel angular pressing (ECAP) with and without back pressure was used for consolidation of fine mechanically alloyed Al-Yttria composite powder. The effect of ECAP on consolidation behaviour of powder, ...
  • Improving the mechanical properties of 2024 Al alloy by cryo rolling 
    Doppalapudi, D.; Venkatachalam, P.; Kumar, S.R.; Ravisankar, B.; Jayashankar, K. (Transactions Of The Indian Institute Of Metals, 63(1), 2010: 31-34)
    Ultra fine grained (1 micron size) materials usually exhibit more strength. Most of the approaches to refine microstructure lead to decrease in ductility. Cryo rolling is a successful technique; samples are rolled at ...
