摘要
本文研究了13Ni(2750MPa 级)马氏体时效钢的疲劳性能及其影响因素。研究结果表明,本合金的单向拉伸疲劳报限为σ(?)的1/4左右。时效条件、变形情况和钢中非金属夹杂物等均影响合金的疲劳性能。
The fatigue property and its effecting parameters of 13Ni Maraging steel (2750MPa) were investigated in this paper.The result obtained show that the single tensile fatigue limit of this alloy is about a quarter of σ_b.The fatigue property of this alloy is affected by aging condition,deformation, non-metallic inclusions and so on.
