Sensitivity of a Number of Physical Properties to Fixation of the Initial Stages of Aging of Fe–14.5% Mo Alloy

Аннотация

Regularities of the change in physical properties (coercive force, electrical resistance, and internal friction) of the Fe–14.5% Mo alloy depending on temperature and time of aging after tempering from the single-phase area were studied. It was shown that the internal friction possesses the highest sensitivity to fixation of the initial stages of aging as compared with other studied physical properties. Data on physical properties are comparable with the peculiarities of the phase-structural transformations observed during aging. The aging modes providing the highest values of the coercive force, which limits the practical value of the studied alloy as a high-coercivity material with the average magnetic energy value, were established.
