style=\"color:red\">断裂</span>,其形貌呈45°斜断口.因为喷丸强化弹簧表层引入的残余应力与外施交变正应力间存在交互作用,所以都利用喷丸强化工艺中的“应力强化机制”提高其疲劳<span style=\"color:red\">断裂</span><span style=\"color:red\">抗力</span>.但21世纪伊始,随着轿车结构的迅速发展,设计者迫切要求弹簧承受的扭转疲劳载荷水平与日俱增,由此导致喷丸强化的弹簧除正断型的疲劳<span style=\"color:red\">断裂</span>外,时而出现纵向或横向切断型的疲劳<span style=\"color:red\">断裂</span>,由此引发疲劳<span style=\"color:red\">断裂</span><span style=\"color:red\">抗力</span>发生显著下降,以往很少出现这种难以理解的现象.目前从事喷丸强化工艺技术的弹簧制造行业很少有文献关注这类问题.文中通过逻辑思维对弹簧的受力分析得出的诠释发现:在切断模式下,喷丸引入的残余应力与外施交变切应力之间不存在交互作用,表明“应力强化机制”在改善切断型疲劳<span style=\"color:red\">断裂</span><span style=\"color:red\">抗力</span>中的强化作用已经基本消失.根据作者提出的喷丸强化工艺原理,喷丸同步引入弹簧表层的是由残余应力与循环弹塑性变形改性的组织结构组成的一对“孪生”,通过分析作者发现,“孪生”中改性的显微组织结构形成的“组织结构强化机制”取代“应力强化机制”起到了改善切断型疲劳<span style=\"color:red\">断裂</span><span style=\"color:red\">抗力</span>的作用.研究结果还表明,优化的喷丸强化工艺必须同时具备“组织结构强化机制”和“应力强化机制”,才能够起到改善正断型和切断型疲劳<span style=\"color:red\">断裂</span><span
