An electron beam physical vapor deposition method was used to fabricate freestanding Y2O3 dispersive strengthened FeCrAlTi foils for high-temperature applications. The vapor incidence mode was found to have great impact on the morphology and crystallographic orientation of the foils. Under symmetric vapor incidence mode, an out-of-plane < 100> fiber texture was formed. While under asymmetric vapor incidence mode, both out-of-plane preference of < 111> direction and several in-plane preferences were developed. As the deposition proceeded, the extent of in-plane orientation increased, and the preferred out-of-plane orientation increasingly deviated from the surface normal. The vapor incidence mode played a role on the growth rate of < 100> direction and < 110> direction, by which the morphology and crystallographic orientation of grains were modified.
