Ni-base superalloy single crystal (SX) mosaicity characterized by the Rotation Vector Base Line Electron Back Scatter Diffraction (RVB-EBSD) method.

Ultramicroscopy, 2019
In the present work we present the Rotation Vector Base Line Electron Back Scatter Diffraction (RVB-EBSD) method, a new correlative orientation imaging method for scanning electron microscopy (OIM/SEM).

Laser Cladding of Ni-Based Superalloys

2020
Laser cladding of Ni-based superalloys has been studied extensively in the recent past owing to their combined properties of high strength and corrosion resistance at elevated temperatures, due to which they are finding wide applications in gas turbine engines, land-based power-generation gas turbines, nuclear and fossil fuel power plants, etc.

Fabrication of nanoporous Ni-based superalloy membranes

Acta Materialia, 2005
Abstract Ni-based superalloys, containing significant quantities of the ordered γ′-phase for precipitation strengthening, are traditionally used as structural materials in high temperature applications. Here we show a new field of application where the self-assembly of the γ′-phase is utilized to produce nanoporous superalloy membranes with ...

Combined Cycle Fatigue of Ni-Base Superalloy

Key Engineering Materials, 2011
Fatigue life of a cast Ni-base superalloy IN 713LC under combined cycle loading consisting of a superposition of low- and high-cycle fatigue at 800 °C was experimentally determined. No measurable effect of combined cycle was found for studied loading conditions.

Hydride formation in a Ni-base superalloy

Metallurgical Transactions A, 1981
X-ray diffraction, optical- and scanning-electron metallographic and microhardness studies have been conducted in pure Ni and a Ni-base alloy (HASTELLOY Alloy C-276) in an effort to determine if hydrides form in the alloy during cathodic charging in the presence of a strong H-recombination poison. The studies indicate that hydrides do form and that the

Ni-base superalloy rods pulled from melts

Journal of Crystal Growth, 1997
Abstract Rods of a Ni-base superalloy PWA-1480 were pulled in the [100] direction with a uniform diameter of 1.3 cm by using a floating-shaper with temperature control of the shaper aperture. The growth process was observed. The resultant dendritic microstructure was examined, including the primary dendrite spacing and the secondary dendrite arm ...

Quantitative microstructural characterisation of Ni-base superalloys

Materials Chemistry and Physics, 2003
Abstract The Ni-base superalloy Waspaloy was investigated as candidate material for rotor and disc applications in steam turbines of the next generation. Quantitative metallography has been performed using various microscopic techniques. Transmission electron microscopy (TEM) and atomic force microscopy (AFM) have been applied for a stereological ...
