The TEM analysis and dilatometric measurements of submicron grained nickel prepared by severe plastic deformation indicate that heating induces the transformation of nonequilibrium grain boundaries to relative equilibrium boundaries. These changes correlate with changes in the saturation magnetization. The nature of this dependence is discussed with respect to the existence of a thin distorted layer in the vicinity of the nonequilibrium boundaries of a submicron grained (SMG) metal.
The microstructure and magnetic properties of cobalt deformed by torsion at high quasihydrostatic pressure and their variations during annealing are studied. A correlation between the hysteretic properties and microstructure after annealing at different temperatures is established. A delay of the γ‐ϵ polymorphous transformation is derived from the temperature dependence of magnetization.
For amorphous Fe83Nd13B4 alloy the saturation magnetization temperature dependence and the kinetics of the alloy crystallization are investigated. The formation of the high coercivity state of the alloy during crystallization is considered. The initial and final temperatures of crystallization activation energy are found as well as conditions for obtaining a maximum Hc.
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.
