The Characteristics of Unidirectional Solidified Ni-Al-Mo Alloys = Charakterisierung von unidirektional erstarrten Ni-Al-Mo Legierungen
The material composite was fabricated by the unidirectional solidification method in the eutectic composition alloy. Performing unidirectional solidification of Ni-Al-Mo alloy in eutectic composition produces γ phase -Ni and γ′ phase-Ni3Al as a matrix, and the phase-Mo growth into fibrous and lamell...
