MonographDOI
Introduction to the high-temperature oxidation of metals
TL;DR: In this article, the authors present a solution to Fick's second law for a semi-infinite solid and a rigorous derivation of the kinetics of internal oxidation, as well as the effects of impurities on oxide defect structure.
Journal ArticleDOI
The implications of chlorine-associated corrosion on the operation of biomass-fired boilers
TL;DR: In this paper, the potential corrosion problems associated with burning biomass fuels either alone or in blends with coal, for electricity production are discussed, and the most severe corrosion problems in biomass-fired systems are expected to occur due to Cl-rich deposits formed on superheater tubes.
Journal ArticleDOI
Measurement of adherence of residually stressed thin films by indentation. I. Mechanics of interface delamination
TL;DR: In this article, a fracture analysis of indentation-induced delamination of thin films is presented based on a model system in which the section of film above the delaminating crack is treated as a rigidly clamped disc, and the crack extension force is derived from changes in strain energy of the system as the crack extends.
Journal ArticleDOI
A flow-partitioned deformation zone model for defect formation during friction stir welding
TL;DR: In this article, a friction stir welding (FSW) metalworking model is proposed which partitions flow through distinct deformation zone geometries around the pin probe and beneath the shoulder, under the effects of the temperature field, constitutive properties, strain rate and pin tool geometry in these zones.
Journal ArticleDOI
Understanding the material flow path of friction stir welding process using unthreaded tools
TL;DR: In this article, an analysis of material flow during friction stir welding is performed using two different pin profiles: a cylindrical tapered pin with flats and an unthreaded pin with flat faces.

Embrittlement by Liquid Metals
TL;DR: In this paper, an electron microscopic investigation of the mechanics of liquid metal embrittlement is described, along with a detailed characterization of the aluminum-gallium couple and its behavior.

Thermodynamics and phase relationships of transition metal-sulfur systems: Part III. Thermodynamic properties of the Fe-S liquid phase and the calculation of the Fe-S phase diagram
R. C. Sharma,Y. A. Chang +1 more
TL;DR: In this article, an associated solution model is applied to describe the thermodynamic behavior of Fe-S liquid, assuming the existence of FeS species in addition to Fe and S in the liquid.

Thermodynamics and Phase Relationships of Transition Metal-Sulfur Systems: II. The Nickel Sulfur System
R. Y. Lin,D. C. Hu,Y. A. Chang +2 more
TL;DR: In this article, the thermodynamic activity of sulfur in the β1-Ni3S2, β2-Ni4S3, γ-Ni6S5 and δ-NiS phases was determined as a function of composition over the temperature interval, 823 to 1023 K, using a gas equilibration technique.
Hot Corrosion in Gas Turbines
TL;DR: The problem of accelerated corrosion of high-temperature gas-turbine alloys in circumstances where sodium chloride or other salts are ingested with the combustion air or in the fuel has been known for many years, and is usually attributed largely to the presence of sodium sulfate as mentioned in this paper.
