Description
Using the nanoindentation technique and the Oliver & Pharr analysis method of the measured loading and unloading segments of the load-displacement curves, the hardness and Young’s modulus were determined for unirradiated and implanted B6O. The implanted hot-pressed B6O was irradiated with 150 keV fluorine in the dose range of 5 × 1014 to 5 × 1016 ions/cm2 at room temperature. The implanted samples showed a decrease in hardness compared to the unimplanted material.
