摘要
研究了高强度手工焊焊缝金属中铜的析出行为。研究结果显示,单道焊焊缝金属中铜难以析出,在多道焊道间热影响区有ε Cu析出颗粒的存在,但析出颗粒尺寸与分布存在不均匀性。
The precipitation of copper in high strength SMAW weld metal (contain Cu 1.48%) was investigated by use of TEM. It is manifested that in single pass weld metal there are no copper precipitations, but in heat affected zone there are some ε-Cu precipitations and the distribution and size of the precipitations are not uniform.
