【摘要】 本文研究了酸性和碱性两种焊剂焊接的BHW35厚板电渣焊缝的冲击性能,测试了转变温度FATT₅₀。在转变温度附近进行了示波冲击试验,从冲击功、断口形态和示波冲击的各种特征值考察了焊剂对冲击性能的影响;并从断裂过程分析了冲击断口各区与相应特征能量的关系。更多还原

【Abstract】 Impact properties of BHW35 electroslag welding metal prepared using acidic and basic flux have been investigated and the transition temperature FATT50 has been obtained in this paper. Instrumented impact tests are conducted near the transition temperature. The effect of flux on impact properties has been discussed in respect to absorbed energy. fracture surface and various characteristic values in instrumented impact test and relationship between different parts on fracture surface and corresponding characteristic energies is analysed with respect to impact process.更多还原
