Sažetak
We report on the results of the Vickers microhardness measurements of the YbxLu1-xAl3 alloy system. It is shown that the Mott-Nabarro theory is not able to explain the concentration dependence of the measured microhardness as is able in some similar Kondo alloy systems containing Ce and U. Interestingly enough, while microhardness increases with the Yb content in YbxLu1-xAl3, it decreases with Yb in the YbxY1-xInCu4 alloy system. Therefore, we try to explain the experimental data taking into account the difference of the electronic structure and the change of the electronic structure with alloying in both systems.
