摘要：

The kinetics of the hydrogen-induced direct diffusive phase transformation in industrial alloy of R2F14B type is studied. The isothermal-kinetics curves of this transformation are obtained for temperatures from 690 to 760 degrees C under hydrogen pressure of 0.15 MPa. The kinetics diagram for direct transformation is obtained. This diagram is similar to ones for the transformations in steels during heating. It is shown that the studied direct phase transformation is a diffusion-controlled one by the mechanism of nucleation and growth.
