Unformatted text preview: wt%Ni = [ ((at%Ni x M Ni)) / ((at%Ni x M Ni) + (at%Cu x M Cu)) ] x 100 Hume-Rothery rules -Conditions for Unlimited solubility 1.Size factor- atoms or ions must be similar in size, no more than 15% difference in atomic radius) in order to minimize lattice s 2. Crystal Structure-must have same crystal structure to avoid transition from one structure to another 3. Valence- ions must have the same valence, otherwise the configuration favors the formation of compounds and not solution s 4.Electronegativity- atoms must have similar electronegativities or else compounds will be favored over solutions Liquidus and Solidus Temperature- Temperature at which material is completely solid or liquid Freezing range = liquidus solidus temperature...
