New methods and techniques for reliable control of quality of advanced engineering materials

Project Details


Rapidly growing market of advanced high-strength steels for automotive production increases significantly the risks and costs of hydrogen-related failures of the vehicle components. We have developed unique thermal desorption apparatus (TDA) and measurement pilot station for precise hydrogen measurements in solids which can contribute significantly in the quality improvement of steels for a variety of applications.
The new TDA enables the sequential measurement of up to five specimens in automatic mode. The TDA capacity is eight measurements in 24 h using the standard measurement procedure (heating rate is 10 C/min, heating range is from RT to 800 C). The high sensitivity of hydrogen spectroscopy measurement (better than 0.003 at.ppm/s hydrogen desorption rate measurement resolution) allows to study the hydrogen interaction with steels, hydrogen trapping, and diffusion. A web-based business platform ( is ready to commercialize the distinguishable services provided by the new TDA concept. This web-based service includes a new approach based on data interpretation using an artificial neural network modeling, enabling a dedicated calculation, for each engineering material, of the sensitivity to hydrogen parameter (HSP).
The proposed techniques have additionally a wide range of industrial applications, where the high sensitivity measurements of hydrogen concentration are required, for instance in electronics industry. Also, development of the hydrogen-based economy and corresponding infrastructures bring challenging demands for the engineering materials, especially in terms of their resistance to hydrogen embrittlement.
