  This book gives a sound review of the present knowledge of the oxidation kinetics and mechanisms of intermetallics. Especially Ti-, Ni- and Fe-aluminides are treated in detail by experts from Europe, USA and Japan.   The oxidation of Ni-Al intermetallic alloys in the beta-NiAl phase field and in the two phase beta-NiAl/gamma'-Ni3Al phase field has been studied between and C. The stoichiometric beta-NiAl alloy doped with Zr was superior to other alloy compositions under cyclic and isothermal by: The oxidation of Ni-Rich Ni-Al intermetallics [microform] / Joseph Doychak, James L.

Peng, in Advances in Brazing, Abstract: Intermetallics have many metallic characteristics, including luster, and electrical and thermal conductivity. Ordered intermetallic structural materials have recently been the focus of many investigations. The physical and brazing properties of Ni–Al system intermetallics, Fe–Al intermetallics and Ti–Al intermetallics are . How to Cite. Grabke, H. J., Brumm, M. W. and Wagemann, B. () The Oxidation of NiAl and FeAl, in Oxidation of Intermetallics (eds H. J. Grabke and M. Schütze. A beta phase nickel aluminide microalloyed with iron having improved ductility. Nickel aluminide intermetallics alloyed with no more than about atomic percent iron have significantly improved room temperature ductility over conventional unalloyed beta phase nickel aluminides or beta phase nickel aluminides alloyed with higher percentages of iron.

An Al/Ni composite coating was deposited on the surface of a pure Ti substrate by arc spray technology and plasma spray technology. In order to enable the in-situ reaction between the Al/Ni composite coating and the specimen, they were heated under different conditions. In addition, oxidation testing was conducted to test the oxidation-resistant property of the coating. Abstract. The °C and °C isothermal and cyclic oxidation behavior of Al 2 O 3 continuous fiber (Saphikon ™)-reinforced/ NiAl composites were ion resulted in formation of Al 2 O 3 external scales in a similar manner as scales formed on monolithic NiAl. The isothermal oxidation of an Al 2 O 3 /NiAl composite resulted in oxidation of the matrix along . The Ni−Al binary syste m contains the following intermetallic phases starting from the Al - rich side: Al 3 Ni, Al 3 Ni 2, AlNi (or NiAl), Al 3 Ni 5 and.
