| Abstract: | The article reviewed the study works about the phenomenon and mechanism that addition of boron induced ductility to polycrystalline Ni_3Al in our country and abroad in the last years. Discussed the polycrystalline Ni_3Al intrinsic brittleness, the state and action of boron in it, the effect of boron to the chemical ordered grain boundary, expriment result and viewpoint of boron duetilizing mechanism on Ni_3Al polyerystal and point out the works which need us to go on study. |
