Popis:	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, microstructure, density and hardness is discussed. The powder was encapsulated in an aluminium can. Room temperature back pressure aided ECAP results in a nearly full denser (97% of its theoretical density) compact at room temperature. Nano Indentation technique was used to determine the modulus of the ECAP consolidated compact.
