摘要：
Different dual-phase microstructures were produced in a steel containing 0.16 C (wt.%) by careful design of the heat treatment schedule in order to study the effect of microstructures, volume fraction of martensite, and epitaxial ferrite on fatigue limit. It was observed that the fatigue limit was raised by an increasing martensite content and aspect ratio, and reduced by the presence of epitaxial ferrite (new ferrite). However, these changes were very clearly and directly related to simultaneous changes in strength.
