In the previous paper it was shown that the strength of brazed joints depended on the method of che test, the dimension of the test piece and the joint clearance. The ground of this hypothesis was that the lateral stress in the rupture of brazed joint increased, as the plastic deformation of specimens concentrated on the part of the filler metal in proportion to narrowness of the joint clearance, and if rupture began in constant shearing stress, the longitudinal stress in the rupture became larger. In this paper further to confirm this hypothesis brazed specimens were broken with impact tester and the broadening of X-ray diffraction line of the broken surface was measured by using Geigerflex. The results showed that the plastic deformation of filler metal increased in proportion as the joint clearance was narrower.
