TY - JOUR AB - From Xray studies of ironnickelaluminium alloys a new phase a was discovered. Although, in the surface layers of these alloys an unstable phase is observed in the early stage of annealing, this phase disappears entirely with prolonged annealing, the Xray pattern showing the coexistence of the a and aphases. In the interiors of the specimens the unstable phase is never found, only diffused Xray interference lines being observed there. However, by very long annealing extending to 3,500 hours at 1,000 deg., the writer succeeded in observing a splitting phenomenon of the Xray pattern in the interiors of the specimens also.
