Microstructure evolution and mechanical properties of B4C/6061Al neutron absorber composite sheets fabricated by powder metallurgy

B4C particle reinforced 6061Al matrix composites is interestingly used for neutron shielding due to its light weight and good strength and neutron absorbing. In this study, B4C/6061Al neutron absorber composite (B4C/6061Al NAC) sheet containing 30 wt% B4C particle was first fabricated by powder metallurgy (hot pressed sintering→extrusion→rolling), then its microstructure and mechanical properties were investigated. It was found that B4C...
