The severe plastic deformation technique that has attracted much attention from the material community in present days is Equal Channel Angular Pressing (ECAP). Ultra fine-grained microstructures can be produced by this technique, without a significant change in geometry. Present work compares Hardness and Raman spectroscopic analysis of CRYO and RT ECAP of Aluminium 6063 alloy. For different aging times, different Raman spectroscopy graphs obtained will be different. The present work's purpose is to make use of Raman intensity ratio(ID/IG) to infer Micro Vickers Hardness of CRYO and RT ECAP of Aluminium 6063 alloy. The Raman spectroscopy utilizing a laser as the light source makes it suitable for measurements of different material properties. In this work, Raman spectra of CRYO and RT ECAPed Aluminium 6063 at different aging timings at 1800c temperature will be analyzed. These results showed good agreement with the age hardening behavior of CRYO and RT ECAPed Aluminum 6063.
