摘要: Experimental evidences show that the material properties in an immediate vicinity of a Grain Junction (GJ) significantly differ from those bulk material. It is assumed near GJs some sort specific phase, and there interface between GJ Hsieh Balluffi’s (1989) experimental data allows us to calculate Laplace pressure at interface. We consider stress field induced by domain. The stresses extend domain compress adjacent grains. In case equilibrium they decrease as r−2 for r→∞ where r distance geometrical center point under consideration, r−1 nonequilibrated case. discuss effect grain anisotropy on generation shear boundaries.
