     A study was made of the fracture mechanism in low cycle impact fatigue andordinary low cycle fatigue of 0.1%C steel by using SEM. It was found that when the plasticstrain amplitude was not quite great,a considerable amount of cleavage pattern appeared inthe fracture surface of low cycle impact fatigue specimens while intergranular fractureappeared in ordinary low cycle fatigue. These reveal the microscopical mechanisms of strainrates effect in low cycle fatigue.

The TEM analysis of substructures of low carbon steel and austenitic stainless steel shows that in ordinarylow cycle fatigue under the definite fatigue life condition of N_f=2×10 ̄3,the dislocation density of both the testedsteels increases with the increase in loading cycles and dislocation arrangement changes from dislocation linesthrough tangles to cells. However,in low cycle impact fatigue under the same fatigue life condition,the disloca-tion array does not change obviously in both steels and only some microtwins...

The TEM analysis of substructures of low carbon steel and austenitic stainless steel shows that in ordinarylow cycle fatigue under the definite fatigue life condition of N_f=2×10 ̄3,the dislocation density of both the testedsteels increases with the increase in loading cycles and dislocation arrangement changes from dislocation linesthrough tangles to cells. However,in low cycle impact fatigue under the same fatigue life condition,the disloca-tion array does not change obviously in both steels and only some microtwins appear with a density not influ-enced by the loading cycles in stainless steel.The strain rate effcets in low cycle fatigue process can be partlyexplained by the variation of the substructures.

组织结构的TEM分析表明,在指定寿命常规低周疲劳过程中,10钢和1Cr18Ni9Ti钢的位错密度随载荷循环周次的增加而增大,组态从线状分布经位错缠结向位错胞转化。而在同样寿命的低周冲击疲劳过程中,10钢位错密庆变化不大,1Cr18Ni9Ti钢出现显微变形孪晶,均不出现胞状位错组态。疲劳亚结构的上述变化部分地解释了低周疲劳过程中的应变速率效应。

A study has been made of low-cycle impact fatigue behaviours of aluminium and duralumin including cyclic stress-strain behaviour,cyclic hardening(softening) and fatigue life.The results show that a fatigue brittleness appears in duralumin and the overload capacity is much lower, while it is a high-strength material.Therefore it is necessary to take care in using the material.

报导工业纯铝和硬铝在常规低周疲劳和低周冲击疲劳载荷下的力学行为,包括应力应变回线、循环硬(软)化及疲劳寿命等。试验结果表明,硬铝既是一种高强度轻金属材料,同时也是一种疲劳脆性材料,过载能力偏低,在构件设计和使用中需予注意。
