description: The subject of the graduate qualification work is: Â«Solid Metal-Induced Embrittlement of titanium alloys in contact with cadmiumÂ». This work was aimed at studying the solid metal-induced embrittlement of titanium alloys. In the course of the work, a review was made of the mechanism and the influence of parameters solid metal-induced embrittlement. The aim of the work is to evaluate the effect of cadmium on the mechanical properties of titanium alloy ÐÐ¢20. By rubbing metallic cadmium of the KÐO grade on the surface of the sample, we simulated the sheathing of plastic cadmium on the surface of a titanium part from the surface of a steel part, an analysis and evaluation of the chemical composition of the surface was carried out, and the change in mechanical characteristics was also considered. The work was carried out on the basis of ÐÐ "ÐÐÐ-ÐÐ»Ð¸Ð¼Ð¾Ð²", where a significant part of the factual material was collected: the results of mechanical tests, fractographic analysis. As a result, a method was developed for determining the cadmium content on the surface of samples, analysis of the morphology and composition of the surface; changes in the mechanical characteristics of the titanium alloy are analyzed. It was found that the ÐÐ¢20 alloy is characterized by a decrease in plastic characteristics by more than 60%. Based on the research conducted at ÐÐ "ÐÐÐ-ÐÐ»Ð¸Ð¼Ð¾Ð²", it was decided that it was impossible to fix titanium parts with cadmium-plated steel fasteners, in order to avoid solid metal-induced embrittlement.
