| Abstract: | Constituents and structure are designed with B phase and Pb as the main elements.The materials with shielded/ structural integrated nuclear shielding are prepared,which have the capacities of neutron/gamma-ray shielding and the mechanical bearing.Through morphology and mechanical properties analysis,the diffusing refinement and control methods of B phase are studied.Laws about the effect of ratio,morphology and distribution of the B phase on strength and ductility of the shielded/structural integration materials are researched.The ways to enhance strength and ductility of the shielded/structural integration materials are further founded. |

| Keywords: | composite nuclear shielding morphology B phase diffusing refinement |
