摘要
The hydrogenation properties of C15 compounds are controlled by crystal structure, the size of the interstitial hole being an especially important factor. Its effect on the hydrogenation properties of MgCu2 substituted with rare earth elements of various radii is discussed and the limit in controlling the crystal structure by conventional substitution is explained.
