A357을 이용한 반응고 상태에서의 브레이징 접합면 분석

Abstract
Aluminum brazing needs normally careful control of temperatures due to little difference between brazing temperatures and melting temperatures of base materials. Unsuitable processing conditions such as brazing temperature, gap between brazed materials, inadequate feeding of flux, etc. can lead to occur joining defects. In this study, A357 was used as a filler metal for the brazing of pure aluminum base materials. A357 was brazed at temperatures in the semi-solid state. Interface microstructures with base materials were observed using OM and SEM/EDS and compared to conventional aluminum brazing.
