THE NI3AL ORDERING SYSTEM.
Abstract
Electrical resistivity, x-ray line positions, degree of order, and microstructures have been investigated for Ni-Al alloys near the Ni3Al composition. The results indicate that Ni3Al undergoes disordering between 1250C and the M.P., also supersaturated gamma, produced in gamma + gamma' alloys by gas-quenching, is extensively ordered prior to gamma' (Ni3Al) phase separation. The latter reaction, if not both, must follow the cooperative phenomena model. Shifts in line position as a function of quench-induced supersaturation are shown. Lattice parameters of equilibrium and non-equilibrium phases are given. (Author)
