Abstract:
Structural changes and the formation of metastable phase states in an Ni3Al-based intermetallic alloy after short-term 5-h annealing at a temperature of 1000°C and upon subsequent multiple deformation of the crystal by compression to 38% at room temperature have been analyzed using transmission electron microscopy and neutron diffraction. © 2009 Pleiades Publishing, Ltd.
