Abstract

The current paper study the hardness behaviour of Kano cattle horn under nanoindentation and micro hardness tests. Five different samples were generated and level A, B, C, D and E cut along the whole length of the horn from the skull to the tip respectively. The samples were indented by diamond Berkovich indenter in sub microns for the nano hardness test. The Vickers micro hardness test was performed using a Wilson Wolpert Vickers micro hardness machine. The results showed that the value of hardness is increasing with the increasing length of the horn. The hardness increased from the skull to the middle of the horn length and starts decreasing gradually to the tip of the horn. Both tests confirmed that the hardness value is approximately higher at the middle of the horn. The range of hardness values of sample A, B, C, D and E obtained using nanoindentation results are 0.24-0.32 GPa, 0.24-0.28 GPa, 0.21-0.24 GPa, 0.22-0.27 GPa and 0.07-0.14 GPa respectively. The hardness value obtained using Vickers micro hardness was 24 VH, 20 VH, 25 VH, 26 VH and 26 VH for A, B, C, D and E respectively.
