摘要：

The present study focuses on the relationship of hardness with grain size for commercially pure titanium (Cp-Ti) and ultra fine grained titanium (UFG-Ti) produced by equal channel angular process (ECAP) of Cp-Ti) Vickers and Knoop indentations of UFG-Ti at different loads was similar to 2 5 times harder than those of Cp-Ti X-ray diffraction (XRD) analysis showed peak broadening in UFG-Ti due to reduced grain size and micro-lattice strains Scanning electron microscopy (SEM) revealed that ECAP had reduced the grain size of Cp-Ti by similar to 10 times Weibull statistics showed UFG-Ti with lower dispersion in hardness values compare to Cp-Ti indicating a more uniform microstructure
