本文综述了超高周次（N > 10（7））疲劳强度和失效机理的研究现状。列出了测试设施。对具有典型S-N曲线的材料进行了分类，并对影响材料S-N曲线的因素如缺口、残余应力、环境等进行了分析。不同的故障机制，特别是发生在VHCF地区，如地下故障，进行了解释。微观结构的不均匀性和统计条件起着重要的作用。所研究的材料是具有体心立方晶格的不同金属，如低强度或高强度钢和调质钢，但也有具有面心立方晶格的材料，如铝合金和铜。
The paper gives an overview to the present state of research on fatigue strength and failure mechanisms at very high number of cycles (N > 10(7)). Testing facilities are listed. A classification of materials with typical S-N curves and influencing factors like notches, residual stresses and environment are given. Different failure mechanisms, which occur especially in the VHCF-region like subsurface failure, are explained. There microstructural inhomogeneities and statistical conditions play an important role. Investigated materials are different metals with body-centred cubic lattice like low-or high-strength steels and quenched and tempered steels but also materials with a face-centred cubic lattice like aluminium alloys and copper.
