It is used to determine the percent weight of liquid and solid phases for a given binary composition and temperature that is between the liquidus and solidus. In an alloy with two phases, α and β, which themselves contain two elements, A and B, the lever rule states that the weight percentage of the α phase is :$X\_\backslash alpha\; =\; \backslash frac$ where * a is the weight percentage of element B in the α phase * b is the weight percentage of element B in the β phase * c is the weight percentage of element B in the entire alloy all at some fixed temperature. == Derivation == Suppose an alloy at an equilibrium temperature ''T'' consists of ''c'' wt% (weight percentage) of element B. Suppose also that at temperature ''T'' the alloy consists of two phases, α and β, for which the α consists of ''a'' wt% B, and β consists of ''b'' wt% B. Let the weight of the α phase in the alloy be $W\_\backslash alpha$ so that the weight of the β phase is $W\_\backslash beta\; =\; W\_\; -\; W\_\backslash alpha$, where $W\_$ is the total weight of the alloy. By definition, then, the total weight of element B in the α phase is $W\_\; =\; aW\_\backslash alpha$, while the total weight of element B in the β phase is $W\_\; =\; b\backslash left(W\_-W\_\backslash alpha\backslash right)$. Together these two quantities sum to the total weight of element B in the alloy, which is given by $W\_B\; =\; cW\_$. Therefore :$cW\_\; =\; W\_B=\; W\_\; +\; W\_\; =\; aW\_\backslash alpha\; +\; b\backslash left(W\_-W\_\backslash alpha\backslash right)$ By rearranging, one finds that :$\backslash frac$ This final quantity is the weight percentage of the α phase in the alloy. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Lever rule」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
