TL;DR: In this paper, the mechanisms of metal damage in the pipe of the main pipeline are investigated, the main reasons for their appearance are found and analysed, and the main results are obtained by joint use of metallography, indentation, method for processing and analysis of digital images.

TL;DR: An automated method for analyzing shapes and sizes of dimples resulting from fracture of titanium alloy VT 23, which can be used in technical diagnostics systems, is proposed in this article, where the developed approaches to the analysis of images of fracture surfaces obtained from scanning microscope allow highlighting the components of the objects under study, performing their morphological analysis, and evaluating the mutual relationship between them.

TL;DR: In this article, an improved dimple image quantitative analysis method based on mathematics morphology was proposed, which allows identifying the elements of the network of dimples of ductile dearing, determining their number, shape and specific share within the analyzed area.

TL;DR: In this paper, the regularities and spatial distribution of multiple cracking of a nanocoating are investigated, and it is found that in the cracking zones the relaxation of the stresses accumulated in the coating takes place; moreover, the intensity of its failure is determined by the structural level of defect accumulation.

TL;DR: In this article, the shape of defects was assessed by the results of digital recognition, and their morphological features were analyzed by taking into account the spatial morphology of fracture and allowing assessing the divergence of dimples from the rounded shape.
