Nowadays, application of nanocrystalline nickel-tungsten (Ni-W) alloys is receiving a great
interest because they are an efficient replacement for hard chromium coatings owing to their …

ABSTRACT A comprehensive review of alloying effects in nickel-based single-crystal
superalloys for turbine blades and vanes operating in a very aggressive environment of …

The chemical, physical, and mechanical characteristics of nickel-based superalloys are
reviewed with emphasis on the use of this class of materials within turbine engines. The role …

Most modern single crystal alloys are thermodynamically unstable with respect to the
formation of topologically close-packed (TCP) phases due to the addition of solid solution …

For the fcc phase of the Ni–Al–Co–Cr–Hf–Mo–Re–Ta–Ti–W system, diffusion data in various
constituent binary systems were assessed to establish a multicomponent diffusion mobility …

The mechanical properties of superalloys are strongly governed by the resistance to
shearing of ordered precipitates by dislocations. In the operating environments of …

The interdiffusivity of Al and the transition metal solutes Ti, V, Cr, Mn, Fe, Nb, Mo, Ru, Ta, W,
and Re in fcc Co is characterized at 1373 K, 1473 K and 1573 K by binary diffusion couples …

A physical model for the creep deformation of single crystal superalloys is presented that is
sensitive to chemical composition and microstructure. The rate-controlling step is assumed …

Abstract The distribution of Rhenium (Re) in a Ni-based single-crystal superalloy is studied
by sub-angstrom resolution transmission electron microscopy (TEM) and energy dispersive …

First-principles calculations for the diffusion of transition metal solutes in nickel challenge the
commonly accepted description of solute diffusion rates in metals. The traditional view is that …
