Dataset on compressive shot peening residual stresses condition in SAE 5160 and DIN 51CrV4 spring steels

This dataset presents measurements of the compressive residual stresses introduced by shot peening in spring steels, specifically SAE 5160 and DIN 51CrV4. These near-surface stresses are vital for extending the fatigue life of critical components such as leaf springs. The dataset focuses on the potential reduction or redistribution of these beneficial stresses during subsequent thermal processes—specifically, paint curing simulations involving oven heating at 80, 160, and 200 °C with varying exposure times. It provides complex, raw quantitative data suitable for validation and reuse in materials engineering and fatigue studies.

本数据集收录了弹簧钢经喷丸处理（shot peening）后引入的残余压应力测量数据，涉及的钢种分别为SAE 5160与DIN 51CrV4。这类近表层应力对于延长板簧（leaf springs）等关键构件的疲劳寿命至关重要。本数据集聚焦于后续热加工工序中这类有益应力的潜在衰减与重分布情况，具体为80℃、160℃及200℃烘箱加热下的涂装固化模拟实验，且实验涵盖不同的保温时长。本数据集提供了复杂的原始定量数据，可用于材料工程与疲劳研究领域的模型验证与数据复用。
