概要
- 論文の詳細を見る
The effects of C, Si, Mn, P and Cu in normalized low carbon steels on fatigue strength are expressed as equations, and the results are extended to higher carbon steels. Sixteen kinds of steels containing above alloying elements are melted according to a statistical design. Tensile and fatigue tests results are analyzed by variance analysis and multiple regression analysis methods. The conclusions are as follows. (1)The correlation among fatigue limits and alloying elements can be expressed with multiple regression equation. (2)Fatigue limit can be expressed as a function of yield strength and quantities of alloying elements. (3)The effects of alloying elements on fatigue limit are similar to those on yield strength.
