Precipitation of Copper in High Strength SMAW Weld Metal

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。

Abstract: 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.
