| 摘 要： | 本文用试验测定和理论计算表明,在多剖面法中利用复合试样测定焊接接头断裂韧性时,可测到的HAZ小区与板厚、试样厚度、线能量、预热温度及坡口角度等因素有关,并非总能测出全部小区的δ_(is)值.对提高测试精度的有关技术问题进行了探讨.

| Abstract: | :Experiment research and theoretical calculation show that the number of determinable regions in HAZ of welds by using the multisection method to measure fracture tonghness is related to the following factor-s: plate thickness, specimen thickness, heat input, preheat temperature and groove angle of the specimen, etc. The Sj, ualue of the regions can not all be measured. The paper also discussed some technical problems relating to improving the measuring accuracy. |
