Thermal Stability of Nickel-Base Alloys
Volume 1: Aircraft Engine; Fans and Blowers; Marine, 2016The thermal stability of three Ni-base samples was assessed at 1850F (1010°C) and 2000F (1093°C) in ambient air as a function of exposure time ranging from 500 to 2000 hrs. Assessments of thermal stability of the samples were made using weight change, oxidation, microstructural evolution, and post-exposure mechanical properties such as Vickers ...

Hydrogen transport in nickel-base alloys
Metallurgical Transactions A, 1992The electrochemical permeation technique has been used to characterize hydrogen transport and trapping in pure nickel and in alloys 600, X-750, and 718 at a temperature of 80 °C. The “effective diffusivity” of hydrogen atoms in alloy 600 is reduced by a factor of about 5 compared to pure nickel.

1987
The scope suggested by the title covers a multitude of widely divergent materials and it would be overly ambitious to attempt an exhaustive treatment in a relatively short paper. Instead, in the overall context of the various alloy families involved, a certain number of areas of potential progress are discussed in the lightof experience gained in the ...

Metal dusting of nickel-base alloys
Materials and Corrosion, 1998Nickel-base alloys are generally less susceptible to metal dusting than steels and the attack is slower. Exposures in strongly carburizing CO-H 2 -H 2 O mixtures at 650 °C and 750 °C have shown, however, gradually increasing attack on the alloys with lower Cr-content.

Aging of (nickel-base) alloy N35KT
Metal Science and Heat Treatment of Metals, 19611. The mechanism of decomposition of the solid solution during aging of a prestrained nickel-base alloy N35KT is similar to the mechanism of decomposition of the solid solution and alloys of the Ni-Ti and Ni-Cr-Ti systems. It proceeds in two stages: the first consists in a redistribution of the atoms of Ti, Ni and other elements in the lattice of ...

Nickel-Base Alloys for Heat Exchangers
CORROSION 2006, 2006Abstract High temperature heat exchangers require the use of oxidation and creep-resistant alloys. Austenitic stainless steels are often specified for reasons of cost, availability, and ease of fabrication. Water vapor, present in the exhaust gas as a by-product of combustion, has been shown to be detrimental to the elevated temperature ...

Thermal Fatigue of a Nickel-Base Alloy
Journal of Basic Engineering, 1965The results of conventional (Coffin-type) thermal-fatigue tests of Hastelloy N are reported. The plastic-strains induced by thermal stresses ranged from a hundred micro-units to more than ten-thousand microunits and correlated well with fatigue life. The slope of the plastic-strain fatigue relationship differs from the conventional slope of minus one ...

Boride phases in nickel-base alloys
Metal Science and Heat Treatment, 19851. The characteristic boride phases in multi-alloyed nickel-base alloys are M3B2 and M5B3. 2. The type of boride phase is determined by the chromium, molybdenum, and tungsten content in the alloy. 3. In alloys in which borides of two types are observed a type M5B3→M3B2 boride reaction is possible during heat treatment and ...

Perforation of a Nickel-Base Alloy Kiln
2019Abstract A kiln, 7.6 m (25 ft) long with a 1 m (3 ft) internal diameter and a 6.3 mm (0.25 in.) wall thickness, is used to regenerate spent charcoal returned by water utilities. This charcoal contains up to 0.57% S and 2.04% Cl. The kiln is made of Inconel 601 (N06601) welded using Inconel 617 (N06617) as a filler alloy.
