耳片型材辐照参量筛选试验研究

Study on the Test for Screening out Irradiation Parameter with Earslice of Templet

用未包铝耳片型材作辐照参量的筛选实验,得到了1gN_f-曲线;在一种应力水平下比较辐照与未辐照试样的疲劳寿命,由实验结果分析可知:选择适当的辐照参量,可改善辐照试样的微观结构,提高其疲劳寿命。

We have made a screen test for irradiation parameter of earslice un-convered with Al and obtained a lgN_f-(?) curve. Comparing the fatigue life of irradiation sample with that of un-irradiation sample on the same level. We have got the results which indicated that sample's microstructure was improved and the fatigue life was increased on condition that a proper irradiation parameter was selected.
