NAB alloys are primarily copper, with substantial alloying additions of nickel, aluminum, and iron. At high temperatures, a body centered cubic (BCC) β phase forms, which typically transforms to a face centered cubic (FCC) α phase interspersed with various κ precipitates upon cooling [1].The microstructure of NAB alloys is sensitive to changes …
