摘 要： Microstructural alterations in bearing steels during rolling contact cycling have been reported in the literature for more than 60years. These changes appear in different shapes and locations. One class of such alterations is butterfly wings: regions of microstructurally transitioned material that appear diagonally around nonmetallic inclusions and may serve as fatigue crack initiation sites. Over the course of the past half a century numerous experimental and multiple analytical efforts have been made to understand and model this phenomenon, yet a lot is to be discovered and understood about root causes and mechanisms leading to butterfly formation. This article presents a comprehensive overview of the crack nucleation phenomena due to butterfly formation, its characteristics, and its negative impact on bearing service life. Significant attempts that have been made to solve the problem over the past half a century are mentioned, with a focus on recent work. Unanswered dilemmas are particularly discussed to highlight avenues of future research.

60多年来，文献中已报道了滚动接触循环过程中轴承钢的微观结构变化。这些变化以不同形态和位置出现，其中一类为“蝴蝶翼”：即在非金属夹杂物周围呈对角分布的微观结构转变区域，可能成为疲劳裂纹的起始点。在过去半个世纪中，人们进行了大量实验和多种分析工作，试图理解和建立该现象的模型，但关于导致蝴蝶翼形成的根本原因和机制，仍有许多待发现和阐明的问题。本文全面综述了由蝴蝶翼形成引起的裂纹萌生现象、其特征以及对轴承使用寿命的负面影响。文中还介绍了过去半个世纪为解决这一问题所做出的重要努力，并重点阐述了近期的研究进展。同时，特别讨论了尚未解决的难题，以突出未来研究的方向。
