摘要：

The temperature dependences of the intensity of elastic diffuse neutron scattering from gamma-FexNi100 - x (x = 57 and 68 at. %) alloy single crystals near basic reciprocal-lattice sites in the (110) plane are measured using a triaxial neutron spectrometer. New effects of instability of the gamma-phase lattice with respect to long-wavelength (transverse and longitudinal) static atomic displacements have been detected. The displacements are found to depend on the iron concentration in the alloys and on temperature. The relations of these structural distortions to premartensitic phenomena and the invar effect in gamma-FeNi alloys are discussed (C) 2004 MAIK "Nauka/Interperiodica".
