Abstract
Hydrogen modifies the internal friction of zone-refined nickel: specimens without hydrogen have high internal friction, due mainly to the movement of dis-locations, whereas specimens with hydrogen have low internal friction which rises after cold working and then decreases as the temperature increases. The results presented are compatible with the idea of pinning of dislocations by hydrogen.Keywords
