本文分析了辐照温度对辐照效应的影响。发现各种铝材在温度高于200℃辐照时都不呈现辐照损伤,而在低于100℃时辐照损伤是严重的。还分析了积分中子通量与拉伸性能之间的关系。发现在通量范围不太大时(30倍以内)幂函数σ=σ_0+(λD)~(1/n)及指数函数σ=σ_0+P(1-e~(-BD))~(1/m)都能给出与实验数据相当符合的结果。最后分析了不同成分铝合金与拉伸性能辐照效应之间的关系。由此估计了某些铝材在低于100℃下辐照到～10~(21nvt)积分中子通量时的拉伸性能数据。
This paper analyzes the effects of irradiation temperature on the effects of radiation. It was found that all kinds of aluminum showed no radiation damage at temperatures higher than 200 ° C, whereas irradiation damage was severe at temperatures below 100 ° C. The relationship between integral neutron flux and tensile properties is also analyzed. It is found that the power function σ = σ_0 + (λD) ~ (1 / n) and the exponential function σ = σ_0 + P (1 -e ~ (-BD)) ~ (1 / m) gives results that are in good agreement with the experimental data. Finally, the relationship between different compositional aluminum alloys and tensile properties of the radiation effects was analyzed. From this, the tensile properties of some aluminum materials irradiated to ~10 ~ (21nvt) integral neutron flux at less than 100 ℃ were estimated.
