Abstract

The influence of a corrosive medium on the characteristics of endurance strength of samples of chrome–nickel steel 38KhNMA was considered. It was shown that, under the conditions of the impact of a corrosive medium, the issue that the endurance strength must be estimated by the results of statistical tests of laboratory samples while bringing the results of their processing in determination of the lower boundaries of scattering of the durability limits and longevities, i.e., to obtaining fatigue curve P = 0, remains of fundamental scientific and practical importance. Fatigue curve Р = 0 determines the endurance strength of a large (full-scale) object in a corrosive medium.

腐蚀环境对疲劳强度特性影响的统计和确定性特征

摘要

考虑了腐蚀介质对38 KhNMA铬镍钢样品耐力强度特性的影响。结果表明，在腐蚀性介质的冲击条件下，必须通过实验室样品的统计测试结果来估计耐力强度，同时将其处理结果用于确定散射的下限，这是一个问题。耐久性极限和寿命，即获得疲劳曲线P = 0，仍然具有重要的科学和实践意义。疲劳曲线Р = 0决定了腐蚀性介质中大型（满量程）物体的耐力强度。
