It showed that a precipitation peak appears at higher temperature than that of H-SK peak, and at same time the latter is decreased in its height after charging. An additional twist shows remarkable influence on the precipitation peak. Aging at the temperature in which O atoms are able to migrate to the dislocations might completely eliminate the enhancement effect. The results indicate that the hydrides might preferentially precipitate on the dislocations. The precipitation peak is considered to be associated with the interaction between the dislocations and the hydrides.
