摘要
采用成组法及升降法针对航天用材料7B50铝合金厚板L-T向试样进行高周疲劳强度研究与测定,摸索材料中值疲劳强度的S-N疲劳寿命曲线的绘制方法,测定出关键材料7B50合金板材的疲劳寿命曲线。
High-cycle fatigue strength of L-T samples for 7B50 aluminum alloy plate for aerospace were researched and determined according to Fatigue test method for metal materials axial loading. Drawing method for mid-value fatigue strength of S-N fatigue lift curve was groped, and fatigue lift curve for 7B50 aluminum alloy plate was determined.
