| Abstract: | Vickers hardness measurements have been made on polycrystalline blanks of CsCl x Br(1−x) and single crystals of NH4Cl x Br(1−x). The composition dependence of hardness is highly nonlinear in both systems and follows an empirical model that includes a lattice contribution and a disorder contribution. The Gilman-Chin parameter (H/C 44) has been calculated and its significance discussed. |
