1. Particle shape varies from long strip to fine globosity after milling. 球磨后粉末形状从原来的长条状转变为细小的球状;
2. Fe element plentifully diffused into welding seam in the form of globosity, while Cu element diffused a little into steel and the soldering seam… 另一方面钢基体与硅青铜焊丝进行氩弧钎焊,铁以球状形式向焊缝中进行了大量的扩散,而铜向铁基母材中进行了少量的扩散,并形成了一条氩弧钎焊缝。
