The characteristic hardness distribution of HPT processed disks with minimum in the centre and maximum at the edges can be easily seen at all strain levels. The hardness values of the monotonically and strain reversal deformed specimens at the same strain level are found to be very similar and shows very similar distribution characterized by higher hardness values at the edge and minimum at the centre which is typical for HPT processed disks. However, the major difference between the hardness distribution of the two processing routes is apparent at the highest strain level i.e. at ԑ=60. At this strain level the hardness at the edge regions (Fig. 6) of the monotonically and strain reversal deformed specimens are found to be very similar ~128 Hv and 125 Hv, respectively. On the other hand, at the centre region the hardness values are found to be different ~107 and 87, respectively, clearly indicating the hardness at the centre of strain reversal deformed specimen is much lower than edges regions and also significantly lower compared to the centre regions of its monotonically deformed counterpart. It is clearly noted that hardness homogeneity is not achieved in any of the processing routes even after the imposition of such huge strain.
