Title
Fabrication of copper Clad High Carbon Steel Rod by Brazing with Brass Filler Metal
이홍로Hong Ro Lee, 이동녕Dong Nyung Lee
Abstract
Copper clad high carbon steel rods have been fabricated by brazing with a brass filler metal. A rapid heating was needed to prevent dezincification which raised the melting temperature of the brass filler metal. The bonding strength increased with heating temperature within the experimental range between 900 and 980℃. There existed the optimum hearting time and brass foil thickness to achieve the best bonding at a given temperature. The results were discussed in terms of the void formation and grain growth in the brass layer, and the capillary flow of liquid brass.
