加载环境对合金超高周疲劳行为的影响
Influence of Loading Environment on Ultra-High-Cycle Fatigue of Alloy Material
摘要
Abstract
Fatigue fracture is related to the energy power, transportation, ocean engineering, metallurgical engi-neering and other fields, which is particularly important in the study of influence concerning low stress and high cycle loading on materials of the key parts in a certain environment. The fatigue cycle is less than 107, which belongs to the category of low cycle or high cycle fatigue. Recent researches on ultra-high cycle fatigue have in-dicated that the metal materials can fail after 107 cycles, which breaks the traditional perception of infinite life. The condition fatigue limit of 107 cycles is not safe for the design of long-life components. In this paper, the re-search status of the ultra high cycle behavior of the alloy material in the special loading environment (tempera-ture and medium) is reviewed in recent twenty years, and its prospect is discussed.关键词
