Features of the HDDR process in alloys based on the SmCo5 compound

“…Indexing of the XRD patterns and the refinement of the lattice parameters were carried out with the help of PowderCell and Lattic programs [6]. The investigation of the HDDR and solid-HDDR processes was realized in the plant described in [7] in the temperature range from 293 to 1215 K and under pressures from 5×10 −3 Pa to 5.0 MPa. The heating rate during hydrogenation, disproportionation (HD) and desorption, recombination (DR) was 5 K/min.…”

Effect of hydrogen on the phase–structure transformations in ZrCrNi alloy

“…The HDDR process was carried out using differential thermal analysis (DTA) [10]. The heating rate in hydrogen and vacuum was 5 • C/min.…”

Features of the HDDR process in R–Fe–B ferromagnetic alloys (R is a mixture of Nd, Pr, Ce, La, Dy and others)

“…The investigation of the HDDR and solid-HDDR processes was realized on the plant described in [15] in the temperature range from 20 to 990 • C at the heating rate 5 • C/min and the pressure from 1 × 10 −3 Pa to 0.1 MPa. Hydrogen was obtained from a thermosorption compressor of hydrogen based on the LaNi 5 compound.…”

“…The research of the behaviour of Dd-Fe-B alloys in hydrogen, in particular the HDDR process, has been reported [15]. This work is devoted to the continuation of the study of the features of the HDDR process in Dd-Fe-B ferromagnetic alloys.…”
