摘要：

The concentrations of forming defects during phase transitions (PTs) and elastic coefficients in the Cu1.95Ni0.05S compound were determined based on differential thermal analysis (DTA) data Delta T-y(T). The sample was studied under the influence of gamma irradiation (at a dose of 25 Mrad) and it was shown that the T-y(T) curves coincide each other before and after irradiation. It was established that alpha, beta, gamma modifications are commensurate when heating the sample. A certain number of defects in S atoms at lattice sites and defects in Cu atoms (also Ni atoms) in interstitial sites of the sublattice are some of the causes of lattice rearrangement.
