Abstract
Molybdenum samples nitrided at 2400 K for 10 min and quenched in the liquid Wood's alloy have been studied by the internal friction /IF/ method. Two relaxational peaks have been observed on the IF curves : A at 392 K and B at 498 K /f=1 cps/. Parameters of the Arrhenius law for both peaks have been determined from their temperature shift /f=1-10 cps/ and from numerical decompositions of the experimental curves into elementary processes. It has been proposed that peak A is one of the dislocational β peaks in bcc metals while B is the nitrogen Snoek relaxation in Mo.
