High Temperature Superplastic Deformationand Magnetic Properties Of The Ni3al Single Crystal

Magnetic propertiesand structureof Ni3Al single crystal alloying with chromium and iron after high temperature superplastic and plastic deformations at 1123 K and 1423 K, respectively have been investigated. Twins and high density of the dislocations were found in the zone of fracture of the alloy after plastic deformation. Dynamic recovery was found as a basic mechanism of relaxation in the alloy under superplastic deformation. By the analysis of the magnetic properties, it is suggested that superplastic deformation does not introduce a composition disorder in studied alloy.
