Phase transformations in a Cu–14.2Al–12.0Ni alloy

The as-quenched microstructure of the Cu–14.2Al–12.0Ni alloy was D0 3 phase containing extremely fine L–J precipitates, where the D0 3 phase was formed by an A2→B2→D0 3 continuous ordering transition during quenching. Besides, the addition of nickel to the Cu–14.2Al binary alloy would raise the B2→β...

Description
Summary:The as-quenched microstructure of the Cu–14.2Al–12.0Ni alloy was D0 3 phase containing extremely fine L–J precipitates, where the D0 3 phase was formed by an A2→B2→D0 3 continuous ordering transition during quenching. Besides, the addition of nickel to the Cu–14.2Al binary alloy would raise the B2→β transition temperature.
