Rare-Earth Metals H2

 The special hydrogen-vacuum equipment for investigation of kinetics of hydrogen-induced diffusive phase (HIDP) transformations in R₂Fe₁₄B (R - Nd, Pr, Dy, Er and other rare-earth metals) and R₂Fe₁₇ (R - Y, Sm and other rare-earth metals) type hard magnetic alloys (Laboratory of Magnetic Materials of the Laboratory of Hydrogen Interaction with Materials) was constructed at first by S.B. Rybalka and then modifyed by V.A. Didus and E.A. Dodonova. This equipment allows to carry out investigation of kinetics of HIDP-transformations in  hard magnetic alloys of this type in hydrogen atmosphere (up to 2 MPa), vacuum (10^-2 Torr) and temperatures range from 300 up to 900^oC by special Sadikov's magnetometrical method [1].
