摘要：
The role of valence electron density on the deviation of the apparent lattice parameter of Al in disordered TM(3d)-Al solid solutions from the true value has been studied. It is shown that this deviation is proportional to the difference in the number of valence electrons between Al and the solvent metals and the trend breaks at the Cu-Al solid solution. This is attributed to the complete occupancy of the d-band in Cu. (C) 1999 Elsevier Science S.A. All rights reserved.
