| 目的 采用小冲杆测试方法测量高能重离子辐照反应堆压力容器A508-3钢的辐照硬化和脆化特性，为工况条件下反应堆压力容器寿命预测提供实验依据。方法 采用兰州重离子加速器提供的高能C6+离子通过减能装置在290 ℃条件下开展A508-3钢辐照实验，并在样品表面形成一定厚度、准均匀分布的离位损伤层。通过开展不同辐照剂量辐照样品的小冲杆测试，得到不同辐照剂量A508-3钢的小冲杆载荷-位移曲线。通过对小冲杆测试得到的载荷-位移曲线的分析，测定不同辐照剂量样品的辐照硬化和脆化特性。结果 压力容器A508-3钢辐照样品的硬化和脆化随着辐照剂量的增加逐渐增强，0.15 dpa以前呈线性增长，而后缓慢增大，约0.2 dpa时达到饱和趋势。结论 通过小冲杆测试可以得到离子辐照样品的硬化和脆化行为，A508-3钢辐照硬化和脆化行为具有一致的变化趋势。 |

| The hardening and embrittlement characteristics of high-energy heavy-ions irradiated reactor pressure vessel A508-3 steel are measured by small punch test method, which provides experimental basis for the life prediction of reactor pressure vessel under working conditions. The high energy C6+ ions provided by Heavy Ion Research Facility are used to irradiate A508-3 steel at 290 ℃ by means of energy degrader, and a certain thickness of quasi-uniform damaged layer are formed on the sample surfaces. The load-displacement curves of A508-3 steel with different irradiation doses are obtained by small punch test. Through the analysis of the load-displacement curves obtained from the small punch test, the irradiation hardening and embrittlement characteristics of the samples with different irradiation doses are determined. The hardening and embrittlement of A508-3 steel increased with the increase of irradiation dose. It showed a linear increase before 0.15dpa, then increased slowly, and reached saturation at about 0.2dpa. The change trend of radiation hardening and embrittlement is consistent. |
