The microstructures and failure behaviours of HSSs were analyzed by electron microscopy.
Microstructure evolution and failure characteristics after furnace cyclic tests at 1100 °C were investigated as well.
The effects of thermal exposure on the microstructure, properties and failure of electron beam physical vapor deposited Al2O3 yttria stabilized zirconia (YSZ) gradient thermal barrier coatings (GTBCs) were studied.
This behaviour can be reproduced by discrete lattices that simulate larger scale constitutive responses, derived from knowledge of microstructure features and failure mechanisms.
It permits the computation of the failure probability of any structure under any mechanical load, solely based on considerations of the microstructure and its failure properties by naturally incorporating the statistical and size-dependent aspects of failure.
Dynamic recrystallization is dominant at strain rates in excess of 10−1 s−1 and results in a strong coarsening of the microstructure and premature failure.
The results could be rationalized in terms of differences in the microstructure and associated failure mechanisms of the thermally grown oxide (TGO) formed on the two bondcoats.
Of particular interest was the notable increase in toughness of the SR-PLA nanocomposite films as a result of their unique microstructure and related failure mechanisms.
