Wasserstoffversprödung

Versprödung von Werkstoffen

Wasserstoffversprödung

Wasserstoffversprödung bezeichnet die durch diffundierenden Wasserstoff verursachte Abnahme von Zähigkeit und Duktilität in Metallen. Wasserstoff lagert sich an Versetzungen, Korngrenzen oder Einschlüssen an, reduziert die Bindungsenergie und erleichtert Rissinitiierung und -ausbreitung. Relevante Mechanismen sind HELP, HEDE und hydride Bildung. Sie tritt besonders bei hochfesten Stählen, Nickellegierungen und Titan auf und wird durch Spannungen, Mikrostruktur und Umgebungsmedien beeinflusst.
