Developing a Method for Assessing the Degree of Hydrogenation of VT1-0 Titanium Alloy by the Acoustic Method

The possibilities of using a nondestructive acoustic method to determine the degree of hydrogenation of  VT1-0 titanium alloy are investigated. The features of using various acoustic parameters to construct computational and experimental methods for determining the porosity of titanium alloy at various stages of its hydrogenation are analyzed. The sources of errors of the proposed methods, the limits of their applicability, as well as the requirements for hardware and software for their implementation are considered. The results of acoustic measurements carried out on samples made of VT1-0 alloy are compared with the ideas about the patterns of its structural changes during hydrogenation process. The possibility is shown for creating engineering algorithms based on the obtained experimental data for assessing the state of the product material subjected to hydrogenation in order to prevent dangerous degradation of its operational properties.
