| Abstract | B4C reinforced Al composites are widely used as neutron absorbing materials (NAMs) due to excellent neutron absorbing efficiency, however, such NAMs exhibit poor high-temperature properties. To meet the requirement for structure-function integration, NAMs with enhanced high-temperature mechanical properties are desired. In this work, a novel (B4C + Al2O3)/Al NAM with netlike distribution of Al2O3 was fabricated by powder metallurgy method and subjected to high-temperature tensile creep test. It was shown that the creep resistance was enhanced by several orders of magnitude via the addition of only 2.1 vol.% netlike-distributed Al2O3. (B4C + Al2O3)/Al exhibited high apparent stress exponents ranging from 16 to 25 and high apparent activation energy of 364 kJ/mol. The creep behaviour could be rationalized using the substructure-invariant model and its rupture behaviour could be described by the Dobes-Milicka equation. |
