摘要
采用冲击试验方法对Q345C钢的低温韧性进行了研究。测定了Q345C钢的冲击吸收功和纤维断面率,对Q345C钢在不同温度条件下的宏、微观断口形貌进行了观察;测试了Q345C钢的韧脆转变温度。结果表明:Q345C钢具有良好的低温韧性。
The low temperature toughness of Q345C steel was studied by impact test method.The impact absorbed energy and fiber section rate of Q345C steel were measured.The macro and micro fracture morphologies of Q345C steel at different temperatures were observed.The ductile-brittle transition temperature of Q345C steel was tested.The results show that Q345C steel has good low temperature toughness.
