Abstract
We report the results of Vickers microindentation hardness measurements on two series of the alloy systems: YbxY1-xInCu4 and YbAgyIn1-yCu4, where the parameters x and y vary from 0 to 1. In both systems the microhardness decreases with increasing the concentration parameters x, or y. Almost the same behavior exhibits the lattice parameter of these systems, which governs evolution of the systems from semi-metallic towards more metallic character. In accordance with that, we ascribe the observed concentration dependence of the Vickers microhardness data to the change of the electronic structure of these systems.
