本文研究用高通量能量流(电子束)辐照铝合金板的裂纹扩展区域,探讨其对疲劳寿命的影响。结果表明,经辐照过的试样比未经辐照的,其疲劳寿命有较大提高。
In this paper, the crack propagation area of aluminum alloy plate was irradiated by high-flux energy beam (electron beam), and its effect on fatigue life was discussed. The results show that the irradiated sample has a higher fatigue life than the non-irradiated sample.
