2. 1. Inconel 718 and Hydrogen

   Author : Niklas Ehrlin; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; IN718 Hydrogen Embrittlement Cathodic Charging;

   Abstract : The nickel based superalloy IN718 is known to be sensitive to hydrogen, causing degradation of its mechanical properties. The degrading mechanism commonly proposed is based on an increased mobility and density of dislocations, caused by the dissolved hydrogen. This results in a decreased yield stress and a premature fracture. READ MORE
