Design of Re-free nickel-base single crystal superalloys using modelling and experimental validations

Modelling and Simulation in Materials Science and Engineering, 2019
Lowering the rhenium (Re) content in nickel-base single crystal superalloys has been a hot topic in recent years. To explore the design space of Re-free nickel-base single crystal superalloys, computer-aid modelling procedures were developed based on ...

Multicycle Fatigue of Single Crystal Nickel Superalloy

Metallurgist, 2018
Multicycle fatigue of an experimental low-alloy single-crystal nickel-base superalloy is studied in relation to crystal orientation and test temperature. It is established that with an increase in test temperature from 20 to 900°C a change is observed in the shape of the multicycle fatigue curve.

Joining of nickel base superalloy single crystals

Science and Technology of Welding and Joining, 2004
The paper reviews scientific and technological issues related to repair weldability of nickel base single crystal superalloys. The role of weld pool geometry and crystallographic orientation of the single crystals on the solidification grain structure was discussed.

Plastic Strain Localization in Superalloy Single Crystals.

1986
Abstract : Nickel-base superalloys are notorious for their inhomogeneous deformation and poor fatigue behavior. Previous studies that the slip was 'planar' or, equivalently, 'coarse' , independent of alloy composition. In this research, single crystal nickel alloys of various gamma prime volume fraction and misfit were deformed under either monotonic ...

Tensile Anisotropy of a Single Crystal Superalloy

2013
To investigate the orientation and temperature dependence of the tensile strength in single crystal superalloys, tensile tests were carried out on a single crystal nickel-based superalloy with three orientations of tensile axis: [001], [011] and [111], in the temperature range from 20 to 1100°C.

Fracture of nickel-base superalloy single crystals

Materials Science and Engineering, 1983
Abstract Single-crystal subsize Charpy impact specimens of a model nickel-base superalloy were machined so as to propagate a crack in two directions through the lattice. Instrumented impact fracture testing was accomplished at ambient and elevated temperatures after which scanning electron microscopy fractography was performed to evaluate the effects
