Abstract
We have investigated the effect of nitrogen and oxygen contaminants within a range of concentrations of 0.05–0.35 % on the mechanical properties and crack resistance of a 2V-type ductile titanium alloy. We have demonstrated that the characteristics of crack resistance in the alloy experience changes that are not uniquely defined as the content of the nitrogen and oxygen increases. We have established a quantitative relationship between the content of the impurities and the geometric parameters of the platelike structure. We have proposed correlation relationships which make it possible to estimate the characteristics of crack resistance in the alloy on the basis of known hardness values and the geometric parameters of the structure.
