Microhardness of the Yb x Y 1 x InCu 4 alloy system: the influence of electronic structure on hardness. Očko, M., Sarrao, J., -., L., Stubičar, N., Aviani, I., Šimek, Ž., & Stubičar, M. *Journal of Physics: Condensed Matter*, 15(50):8719-8723, 12, 2003. Website abstract bibtex We show that the Vickers microhardness, measured on flux grown single crystals of the YbxY1-xInCu4 alloy system, although sample dependent, exhibits clear concentration dependence; it increases with decreasing x. Such a dependence is not expected because the cubic lattice parameter increases with decreasing x and one expects then a decrease of hardness with decreasing x. Also, such a concentration dependence is in accordance with neither the Mott-Nabarro theory nor other known experimental results. We ascribe the observed dependence to the change of the electronic structure of the YbxY1-xInCu4 alloy system with x.
