Beschreibung
Zusammenfassung:The phase composition, crystal structure, and physical properties (magnetization, electrical resistivity, thermoelectric power, relative elongation, and thermal expansion coefficient) of the stoichiometric alloy [Ni.sub.50][Mn.sub.25][Ga.sub.25] and nonstoichiometric alloys [Ni.sub.50-x][Cu.sub.x][Mn.sub.29][Ga.sub.21] (x = 0, 1, 2) with the thermoelastic martensitic transformation have been investigated. The influence of the chemical composition on the transformations and physical properties of the alloys has been determined.
