Effect of quenching in a magnetic field on the structure and properties of sintered magnets from an SmCo5 alloy powder

Conclusions Quenching in a magnetic field has a beneficial effect: It increases the coercive force of a magnet from a SmCo₅ alloy powder. Thermomagnetic treatment results in freezing of magnetic and phase- and-structure changes in magnets.Translated from Poroshkovaya Metallurgiya, No. 7 (259), pp. 37–42, July, 1984.     

Superconductive toroidal solenoid of Tokamak-7

Conclusions Our tests have shown that the superconductive magnetic system of the T-7 unit is operative and that the main design and circuit features adopted on the basis of preliminary investigations are appropriate. In particular, it was shown that it is possible to use a hydraulic parallel joining of numerous sections without additional adjustment. The superconductive magnetic system could be efficiently cooled by liquid two-phase helium rather than by supercritical cold helium which was frequently discussed in the literature.The authors sincerely thank the friendly collective of engineers, designers, technicians, and workers who enthusiastically applied their efforts to the building of the Tokamak-7 unit and the execution of the tests.Translated from Atomnaya Énergiya, Vol. 45, No. 3, pp. 171–174, September, 1978.
