The kinetic coefficients, i. e. the electrical conductivity, thermal conductivity, and thermo e.m.f. of a binary ordered alloy are calculated on the basis of the many-electron model of an alloy previously used in [l] taking into account the non-equilibrium of the phonon system. It is shown that a t low temperatures phonon drag becomes important and leads to qualitatively new temperature dependence of the kinetic coefficients as compared to pure metals. Under definite conditions in the electrical resistivity vs. temperature curves a minimum and maximum may occur.
A generalization of the s-d-exchange model developed for domains in binary antiferromagnetic alloys is presented. It is shown that departures from the the ideal periodicity in the distribution of atoms among the lattice sites leads to a number of interaction processes between elementary excitations in the electron and spin sub-systems which do not occur in ideal antiferromagnetics. I n particular, electron-magnon collisions arise which do not conserve quasi-momentum. In the low temperature range these effects are dominant in the scattering of conduction electrons, giving rise, to a term proportional to TZ in the electrical resistivity.
An investigation is made of the evaporation heat and the equilibrium vapor pressure over the crystal containing vacancies. It is shown that in the case of a monoatomic crystal the vtacancies reduce both of these characteristics; the same effect takes place in a dilute intersitial alloy. In the case of dilute substitutional alloys the vacancies reduce both the vapour pressure and the evaporation heat of the host component and increase the impurity vapour pressure. It is found that the coefficient of the isotope separation changes considerably due to the vacancies.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
