Unformatted text preview: Altering T can change the number of phases Components and Phases Components the elements or compounds which are present in the allow Phases the physically and chemically distinct material regions that form Criteria for Solid Solubility Simple system o both have the same crystal structure and have similar electronegativities and atomic radii (W. Hume-Rothery rules) suggesting high mutual solubility o Ni and Cu are totally soluble in one another for all proportions The Lever Rule Tie line connects the phases in equilibrium with each other -> also sometimes called an isotherm Binary Eutectic Systems Eutectic liquid transforms to two solid phases Eutectoid one solid phase transforms to two other solid phases Peritectic liquid and one solid phase transform to a second solid phase...
