Grain-boundary grooving technique

A technique has been developed for the study of mass transport at internal interfaces in composite systems. For the process of grain boundary grooving the linear dimensions of the profile develop as at high tempera-... [Pg.313]

Samples of polycrystalline material were studied at 750 to 1050C by using a groove and stain technique. It was shown that the Fisher model for grain boundary diffusion accurately described the data when an infinite source was assumed. It was found that the grain boundary diffusivity was described by ... [Pg.111]

Fig. 5. Schematic of groove observation technique with Zeiss interference microscope. Focusing at A yields the external dihedral angle, which depends on the ratio of surface to grain boundary tension. Focusing at B yields the internal dihedral angle, which depends on the ratio of interfacial to grain boundary tension. Fig. 5.
