Effect of heating rate on microstructure of brazed joints with STS 304 Printed Circuit Heat Exchanger (PCHE),which was manufactured as large-scale(, mm), have been studied to compare bonding phenomenon. The specimens using MBF 20 was bonded at for 1hr with and heating rate, respectively. In case of a heating rate of , overflow of filler metal was observed at the edge of a brazed joints showing the height of filler metal was decreased from to . At the center of the joints, CrB and high Ni contents of -Ni was existed. For the joints brazed at a heating rate of , the height of filler was decreased from to showing the overflow of filler was not appeared. At the center of the joints, only -Ni was detected gradating the Ni contents from center. This phenomenon was driven from a diffusion amount of Boron in filler metal. With a fast heating rate , diffusion amount of B was so small that liquid state of filler metal and base metal were reacted. But, for a slow heating rate , solid state of filler metal due to low diffusion amount of B reacted with base metal as a solid diffusion bonding.
