321不锈钢蠕变性能数据集

现代工业对高效、环保的要求日益严苛，特别是石油化工等领域的关键装备逐渐朝着高参数、大容量和恶劣条件运行方向发展。这些关键装备除了经受长时间运行和变负荷导致的机械及热应力循环载荷以外，还会经受稳态运行引起的蠕变载荷，因此，这些关键装备不可避免地面临更加复杂的蠕变和疲劳损伤。疲劳与蠕变的作用可能导致高温关键装备提前失效，造成灾难性的后果，因此，高温关键装备的设计和完整性评价必须考虑蠕变和疲劳作用的影响。因此，研究金属材料的失效问题就显得尤为重要。目前，不锈钢的高温蠕变和疲劳性能研究已经成为钢铁领域中的重要研究课题。通过实验表明，GBE样品高温蠕变性能优于非GBE样品，蠕变寿命提升70%以上，蠕变极限比非GBE样品提高10.2%。

Modern industry has increasingly stringent requirements for efficiency and environmental protection. Particularly, key equipment in fields such as petrochemical industry is gradually evolving toward operation under high parameters, large capacity and harsh conditions. These key equipment not only undergo cyclic mechanical and thermal stress loads caused by long-term operation and variable loads, but also suffer from creep loads induced by steady-state operation. As a result, these key equipment inevitably face more complex creep and fatigue damage. The combined effects of fatigue and creep may lead to premature failure of high-temperature key equipment, resulting in catastrophic consequences. Therefore, the design and integrity assessment of high-temperature key equipment must take into account the impacts of creep and fatigue. Thus, research on the failure of metallic materials is particularly critical. Currently, research on the high-temperature creep and fatigue properties of stainless steel has become an important research topic in the iron and steel industry. Experimental results demonstrate that the high-temperature creep performance of GBE samples outperforms that of non-GBE samples, with the creep life increased by more than 70% and the creep limit improved by 10.2% compared to non-GBE samples.
