查询词典 alloy

In fact, the total energies for the possible metastable alloy phases of A〓B and AB〓 types of six possible structures were calculated as a function of their lattice constant to find out if the respective metastable phases of A〓B or AB〓 types could be relatively stable in the selected systems. The calculation not only predicted the possible metastable states but also the lattice constant of the corresponding metastable alloy phases of either FCC or HCP structures.
