Elastic Anomalies

AbstractLarge single crystals of KNElastic properties and thermal expansion reflect the close relationship to the CsCl-type structure. The anisotropy is mainly caused by the preferential orientation of the long axes of the anionic dumb-bells within one distinct plane. KSCN exhibits weak elastic anomalies approaching the phase transition at 413 K. These effects, which are much smaller than those found in the high-temperature phases of the alkali cyanides, indicate, together with the almost missing hysteresis and the small transition enthalpy, a transition of mainly second order. The variation of the elastic behaviour of KHF

ABSTRACTElastic properties, thermal expansion and deformation behavior of Cr5Si3 with the D8m structure were investigated using single crystals. From the values of Cauchy pressures as well as the ratio of the polycrystalline bulk modulus (B) to shear moduls (G) estimated from single-crystal elastic constants (cij), deformation behavior of Cr5Si3 is expected to be relatively brittle compared to Mo5Si3 with the same crystal structure. However, plastic deformation of Cr5Si3 is confirmed above 900 ~ 1100 °C depending on the loading axis orientations.
