残余应力是指产生应力因素消失 ( 如：载荷去除、加工终止、温度均匀、相变完成等 ) ，但形变、体积变化仍不均匀，为保持平衡而在 构件内部存留应力。残余应力是构件力学性能最主要的影响因素之一，如拉伸残余应力会降低拉伸屈服极限、提高压缩屈服极限，压缩 残余应力正好相反 ; 宏观残余应力会产生形变、并影响疲劳寿命，微观残余应力导致组织内产生微裂纹发生脆性破坏。在服役过程中， 残余应力与工作应力叠加容易产生二次变形和应力重新分布，产生变形、开裂、耐腐蚀性能及构件整体稳定性下降，如当交变荷载工作 时区域应力达到屈服点时会产生局部塑性变形 ; 高温工作条件下产生高温蠕变开裂 ; 腐蚀环境下产生应力腐蚀开裂。 残余应力测量是通过实验测试方法了解构件残余应力分布的技术，尤其适用于复杂构件。主要分为有损测试法（如钻孔法、切槽法）和 无损测试法，其中钻孔法应用广泛，通过应力释放原理测量应力。 中国市场规模现状及未来趋势 残余应力是零件表面完整性质量的关键评价指标，直接影响着零件的开裂失效、加工变形和尺寸稳定性。通过残余应力检测和量化分 析，能够对加工工艺评估和工艺优化提供量化依据，能够实现零部件变形及失效问题分析和针对性解决，实 ...
