Investigation of the completeness of specimen degassing in an analysis of the hydrogen content of aluminum alloys

Experiments and mathematical modeling of the dynamics of the heating of metallic specimens and the diffusion of hydrogen inside them show that not all the hydrogen which has a high bond energy is extracted from the specimens by the method of melting them in a stream of a carrier gas. This finding mi...

Zusammenfassung:Experiments and mathematical modeling of the dynamics of the heating of metallic specimens and the diffusion of hydrogen inside them show that not all the hydrogen which has a high bond energy is extracted from the specimens by the method of melting them in a stream of a carrier gas. This finding might present serious obstacles to reliably determining hydrogen content by this method in aluminum-magnesium and aluminum-lithium alloys.
