摘要
采用光学显微镜分析硼对低合金Q345钢板微观组织和物理性能的影响。结果表明，在其他条件基本一致的情况下，加入0．0017％硼对低合金Q345钢板的金相组织、力学性能、冲击性能和焊接性能影响均较小。
The effects of boron on the microstructure and mechanical properties of low alloy Q345 steel were studied by using optical microscope. The results show that, when other conditions were basically the same , it was less influence on the microstructure and the mechanical properties of low alloy Q345 steel after adding 0. 001 7% B, and the welding performance was less affected.
