Abstract:

The precipitation of the beta phase hydride from the solid solution has been studied using a variety of techniques including T.E.M., S.E.M., internal friction and resistivity methods. The effects of accommodation of the volume change which accompanies the beta phase precipitation is examined. A discussion of the solute effects on the alpha-beta solvus is presented. Stress effects on the alpha-beta solvus is discussed. In addition, some of the properties of the beta phase hydride is described.
