摘要：高温结构的疲劳失效是与时间相关的,建立这一失效机制下的断裂理论和寿命评价技术,进而控制结构失效是人们多年来努力的目标.从裂纹扩展控制参量、裂纹扩展规律和寿命评价技术、材料老化与环境因素影响和结构完整性评定工程方法等几个方面,对近年来这一领域的研究进展进行了总结,并对今后该领域的发展方向进行了预测.
Fatigue failure of high temperature structures in power engineering and petrochemical industry is time dependent. In order to establish the corresponding fracture theory, develop a proper life assessment approach and then control the structure failure, many studies were carried out on this type of failure mechanism in the past years. In the present work, the recent development is reviewed in the follow parameters for crack extension, rules of the crack growth and residual life estimation, ing infl aspects： fracture uences of materials aging and environment factors, and engineering approaches for structural integrity assessment. Research achievements in this field are summarized and some suggestions are presented based on the literature
