The correlation between the valence electron counts and the stabilities of intermetallic phases and stmctures were also espoused by others, like the physical chemists Neds N. Engel (b. 1904) and Leo Brewer (1919-2005), although Hume-Rothery found their result somewhat controversial. The Engel-Brewer theory asserts that the crystal stmctures of transition metals and their intermetallic compounds are determined solely by the number of valence s and p electrons. For example, Engel suggested in 1949 that the BCC stmcture correlated with (where n is the total number of valence...

The X-ray diffraction studies were carried out at the U.C. Berkeley CHEXRAY facility with the assistance of Dr. F. J. Hollander. The authors express their gratitude to Professors David H. Templeton, Leo Brewer, and Herbert L. Strauss for useful discussions pertaining to the lattice energy calculations. 

In many instances, estimates were necessary to carry out the calculations. Even for the elements a surprising amount of experimental data are necessary to put the tables on a firmer basis. It is hoped that research workers will take note of these gaps and endeavor to fill them when they have the equipment and materials on hand. Thermodynamics can be an extremely powerful tool, but its edge is severely blunted when the fundamental starting data are lacking. Berkeley, California Leo Brewer...
