AbstractThis study explored the impact of microstructure and residual stresses on the fracture behavior of as‐deposited thermal barrier coatings (TBCs). Two distinct air plasma sprayed TBCs, Coating A (conventional lamellar porous) and Coating B (dense vertically cracked), were investigated. Coating A involved coarser but less dense powders as feedstock and a lower substrate temperature during deposition. Further, Coating A had times higher randomly oriented porosities, finer grains, lower hardness, and elastic stiffness. Strikingly, however, the fracture strength was higher for the porous as‐deposited Coating A. The answer to this apparent contradiction emerged from the intergranular residual stresses. These were measured using both X‐ray diffraction and high‐resolution‐electron backscattered diffraction. Coating B, deposited at a higher substrate temperature, had clear growth selection of oriented grains. These also had more out‐of‐plane normal and shear residual stresses. The growth selection induced residual stresses appeared responsible for the decohesion of Coating B from the substrate and, correspondingly, lower fracture strength.

ABSTRACT Transformation-induced plasticity mechanism is a very interesting phenomenon wherein a certain amount of austenite, which is thermally stable at room temperature but can be transformed to martensite during deformation, is retained in the microstructure. The amount of deformation (either by tensile, compressive or shear) that the austenite regions can withstand before they transform to martensite depends on their stability which is a function of the chemical-free energy and the severity of straining. In the current work, a bainitic steel with some retained austenite (RA), exposed to sliding wear in a pin-on-disc wear testing machine, was considered for the study. This paper aims to quantify the shear strain developed in the deformed subsurface region due to wear by using a simple image digitisation technique, and the stability aspect of RA for a complicated deformation mechanism like wear was studied considering the thermodynamics of austenite to ferrite transformations.

Sliding wear behaviour is a very complex procedure where several parameters, including nature of the two abrading bodies and variables related to the conditions under which the actual experiments were conducted, may influence the final material loss. Disentangling these parameters will improve the understanding and the predictions can be compared with the performance of the existing materials. An attempt was made in the current work to develop a model, considering several material specific variables (e.g. composition, microstructure, hardness, etc.) along with the experimental conditions (load, distance, temperature, etc.). The predictions were quite consistent with existing knowledge. The model was also validated with actual experiments with varying load and distance slid conditions which were never known to the model.
