Abstract:Kinetics of hydrogen-induced reverse phase transformation, i.e. recombination process of decomposed of YH 2 hydride phase and α-Fe phase of iron in initial phase of Y 2 Fe 17 hard magnetic alloy has been studied. It has been established that, as the temperature increase from 650 to 750 ⁰ C, a reverse phase transformation significantly accelerates. The activation energy of phase transformation process has been determined from kinetic data (227÷383 kJ / mol) that it is correspond to the values of activation ener… Show more
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.
