This paper has investigated how to evaluate the dependence curves of impact toughness orfracture toughness vs temperature on nuclear pressure vessel A508CL3 steels by use of standardCharpy-size specimen and the eight reconstituted Charpy-size specimens which were manufactured from the two broken halves of the tested standard Charpy-size specimen. The researchresults indicate that a reliable and complete dependence curve of impact toughness or fracturetoughness vs temperature can be obtained by means of only one standard Charpy-size specimenand the eight reconstituted Charpy-size comPOund specimens which were manufactured from theformer. This is very valuable for improving the reliability of surveillance on nuclear pressurevessel embrittlement due to neutron iradiation. Especially, this method is extremely importantfor the life-time prediction and safety surveillance of a nuclear pressure vessel which has operated for a long-time and where there has been a few surveillance specimens remained.

用一个标准Charpy试样及试验过的该试样的两个半截试样所获得的8个“再造Charpy复合试样”评定核压力容器用A508CL3钢冲击韧性或断裂韧性的温度转变曲线。研究结果表明,用这种方法可得到一条较为可靠而完整的核压力容器钢的冲击韧性或断裂韧性随温度的转变曲线。这相当于在核监测计划中,只需取出一个Charpy试样即可得到完整的材料性能曲线,这对于提高核压力容器中子辐照脆化监测的可靠性很有价值,特别是对于运行时间较长(堆芯内监测试样数量已经不多)的核容器寿命预测和安全监视尤为重要。

This investigation has used the five methods to estimate the dynamic fracture toughnes for a nuclear pressure vessel steel A508CL3 by using instrumented impact test and pre-cracke Charpy-size specimen, the merits and the disadvantages of the five methods have also been compared. The experimental results indicated that the maximum load energy method based on the curve of load versus load-point diaplacement overestimates the dynamic fracture toughness, especially beyond the room temperature. However . the method of compliance changing rate underestimates the dynamic fracture toughness. The method of measuring the stretched zone width (SZW) at the crack tip by means of a SEM fractography and then converting SZW into JId have a relatively large error, and it is difficult to measure the SZW and with high rost. The method of energy revised at the maximum load may be considered as a better single specimen method for determining dynamic fracture toughness of a A508CL3 steel. Furthermore, the results indicate that although the dynamic resistance curve method can exactly estimate dynamic fracture toughness of the material, this method needing several specimens and the test procedure is complicated, thus, it is not suitable for nuclear reactor pressure vessel embrittle-ment surveillance due to neutron irradiation.

采用示被冲击试验及预制疲劳裂纹Charpy试样,通过几种不同的单试样(或多试样)试验方法对核压力容器用A508CL3钢的动态断裂韧性进行了评定,比较了各种方法的优缺点.研究结果表明:最大载荷能量法过高地评定了材料的动态断裂韧性值(特别是在常温以上温度时);而柔度变化率法的评定值则过低,断口延伸带宽度测试法的评定结果具有较大误差,且试验过程复杂,成本较高;能量修正法是一种方便而精确的评定核压力容器钢动态断裂韧性的单试样方法;研究还表明,虽然动态阻力曲线试验法可获得最为精确的动态断裂韧性的临界值,但所需的试样数量较多,用作核压力容器钢的中子辐射脆化动态断裂韧性监测是不合适的.

Instrumented charpy impact can become more useful by connecting the digital memory and microcomputer. The dynamic fracture toughness K Id , for nuclear power plant pressure vessels steels were measured with a fatigue pre cracked type charpy specimen. Test results show that the crack initiation in the fatigue pre cracked specimen of AEME SA508.cl.3 steels occurs prior to the maximum load, and the effects of irradiation on Δ T 100 for AEME SA508.cl.3 steels is less than that of Δ T 41J...

应用预裂纹示波冲击法研究核压力容器钢辐照后动态断裂韧性KId测试方法。结果表明:预裂纹试样的裂纹扩展始于其最大载荷之前,辐照对动态断裂韧性ΔT100的影响小于对冲击韧性转变温度ΔT41J的影响。
