Microfissuring meaning

WebThe microfissuring in the heat-affected zone (HAZ) of electron-beam- (EB-) welded thermomechanically processed INCOLOY 903 has been studied with a view to reducing the incidence of microfissuring and to obtaining a better understanding of the influence of EB welding parameters on it. Webmicrofissuring susceptibilities, they all showed the same microfissuring sequence. Figure 2 shows evolution of NbC into liquid and finally Laves phase. Figure 3 depicts our scheme of the microfissure formation in the presence of this intergranular liquid. Several important conclusions can be drawn from the results of this study.
