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 ].
