Abstract Scope |
Aluminum matrix composites reinforced by B4C are of interest as radiation-shielding material. B4C has the advantages of a high melting point and hardness as well as neutron absorption and shielding properties from the nuclear reaction with 10B. Hence, aluminum matrix composites containing B4C exhibit high specific strength, hardness, and radiation-shielding ability. However, weak interfaces due to poor wettability between B4C and aluminum deteriorates the performance of B4C/Al composites.
In this study, aluminum composites containing 1.5, 3, and 5 vol.% B4C were produced by hot rolling mechanically milled composite powder and heat treatment to partially decompose the B4C particles. This allowed B and C atoms to intercalate into and then distort the aluminum lattices. We shall discuss the effect of the interfacial features, varied by the heat treatment durations, on the strengthening behavior of B4C/Al composites. |
