TL;DR: In this article, a statistical approach is proposed for the prediction of the life of thermal barrier coating (TBC) systems, which is based on a criterion linked directly to the dominant failure mechanism and relies on a statistical treatment of the TBC's morphological characteristics, non-destructive stress measurements and on a continuum mechanics framework to quantify the stresses that promote the nucleation and growth of microcracks within TBC.

TL;DR: In this paper, the effects of residual stresses arising from thermal expansion mismatch are taken into account, and a series of very useful inter-relationships between thermo-elastic constants for damaged and corresponding undamaged laminates are derived.

TL;DR: In this article, a theoretical analysis has been made of the combined effects of reversible and irreversible trapping on hydrogen transport in steels, coupled with repetitive electrochemical permeation measurements to characterise the diffusion and trapping parameters associated with a 13% Cr martensitic stainless steel commonly used for oil production tubing.

TL;DR: In this paper, the available data for the measurement of viscosity of aluminium and its alloys are reviewed and most measurements are performed with an oscillating vessel technique and the merits of this technique are discussed.
Abstract: In this paper the available data for the measurement of viscosity of aluminium and its alloys are reviewed. Most measurements are performed with an oscillating vessel technique and the merits of this technique are discussed. The purity of the aluminium affects the measured viscosity values and we recommend a value of between 1.0–1.4 mPa·s for the pure element at the melting point. Although studies of the viscosity of aluminium alloys are limited, the effects of elemental additions to the alloy are similar to those for additions to the base metal. Thus an increase in concentration of Ti, Ni, Cr, Mn, Mg tends to increase the viscosity whereas the viscosity decreases with increasing Zn and Si concentrations. Also purification of an alloy decreases the viscosity. There is a wide variety of models ranging from those based on empiricism to thermodynamic methods. With the present quality of input data it is probably better to use a simple rather than a sophisticated model.

TL;DR: In this article, thin films of Cu 2 O and CuO are deposited by RF reactive sputtering at different substrate temperatures, and they are identified by grazing angle X-ray diffraction (GAXRD).
