研究了电沉积纳米晶纯Ni和超细晶冷磨铝镁合金的疲劳响应。结果表明，晶粒细化通常会提高材料在应力控制疲劳下的抗破坏能力，而对疲劳裂纹扩展的抗破坏能力则有不利影响。(C) 2003材料学报。Elsevier Ltd.出版。版权所有。
The fatigue response of electrodeposited nanocrystalline pure Ni and a cryomilled ultra-fine-crystalline Al-Mg alloy was studied. It was found that grain refinement generally leads to an increase in resistance to failure under stress-controlled fatigue whereas a generally deleterious effect was seen on the resistance to fatigue crack growth.
