                    材料的JR阻力曲线是核工程结构断裂过程的稳定性和失效评定的重要基础.本研究采用美国ASTME813标准和国家标准GB2038-80测定了核电站压力容器用A508CL3钢及其窄间隙埋弧焊焊缝的JR阻力曲线,并研究了试样尺寸对JR阻力曲线的影响.
                
                JR resistance curves of materials are more imPOrtant foundation to estimate the stabilityand failure for nuclear engineering structure. This studies have determined the JR resistancecurves of nuclear power station pressure vessel steel A508CL3 and its weld welded with narrowgap submerged-arc welding process by means of ASTM E813 and GB2038 methods. The innuences of specimen size on JR resistance curves have been discussed.
