Research Abstract

In the present investigation, using specimens with different strain and strain gradient prepared by high pressure torsion machine, the effect of strain gradient on the strengthening and refinement of microstructure were studied. The measurement of hardness for HPTed pure metals such as Al, Ti, Ni, Cu, Fe revealed that recrystallization takes place in the pure metals with low melting point such as Al and Cu. Pressure induced transformation was observed in pure Ti. Thus using pure Fe in which only the effect of strain and strain gradient appears, the effect of strain and strain gradient on the hardness was studied. The clear strain gradient hardening was observed in the HPTed pure Fe. The HPTed Fe showed the ultimate tensile strength of 2GPa, and the total elongation increased with applied strain. The effect of high pressure during HPT was examined using pure Ti which transformed from phase to w phase when HPTed at high pressure. The volume fraction of CO phase increases with strain and with decreasing oxygen content. The co phase is metastable at ambient conditions and it transforms back to a phase during heating.
