Microhardness Study of Some Novel Compounds and Alloys

Vickers microhardness has been measured at room temperature on a numerous single-phase alloys and compounds (all together on 41 samples having different composition) which contained Ce(4f) and/or U(5f) metals. The significant changes were observed for all examined series of chosen systems with the discernible maximum or minimum in the microhardness curves. While the maximum in curves could be easily explained by the existing theories, explanation of the observed minimum needs additional studies.
