Webgrain boundary energy is given as the energy value between two grains of the same phase. I think that says it all. A "grain" of a material is surrounded by boundaries, but they are only grain boundaries if the neighbor is of the same phase. The boundary is only a phase boundary if the neighbor is a different phase. Web2 days ago · Grain boundaries provide nucleation points for Laves phase [27], therefore grain boundaries density will affect the precipitation of Laves phase to a certain extent. As can be seen from Section 4.1 , grain size gradually increased with the increase of Al element, so grain boundaries density gradually decreased [ 23 ].
