The use of Pettifor structure maps for the interstitially stabilized AB{sub 3}C-Cu{sub 3}Au intermetallics
For a long period of time scientists have been trying to classify and order the crystal structures of binary, ternary, and quaternary phase. Pettifor set up a chemical scale X by arranging the elements along a single axis. The order of the elements preserve the Mendelev type characteristics of the periodic table. Each element has been assigned a number (Mendeleev-number) according to its order. This ordering of the elements has not created any overlap between the (VB, VB, and VIB) adjacent groups. Several two dimensional structural maps were constructed using (XA, XB). Such maps have achieved good structural separation. The boundaries of the structural domains in the Pettifor maps are meaningless and only define the areas of high potential of certain structure type to occur. The Pettifor maps can be used as a guide to structural changes due to substitutional alloying.
