Description
Summary:By example of determination of the fractal dimension on a photo of the profile of Palmqvist microcrack obtained as a result of indentation of a Vickers indenter to the surface of a section of metal-ceramic solid alloy (MSA) based on titanium carbonitride, the relationship of microstructure parameters to the characteristic features of the destruction caused by the development of microcrack is studied. An attempt to find the numerical values of the fractal dimension of microcracks is made. As a solid alloy based on titanium carbonitride, alloys of KNT3, KNT7, and KNT12 grades are selected, where the number indicates volumetric content of the binder phase of Ni–Mo in the alloy, respectively.
