| 英文摘要 | B4C/Al 4 C/Al composites are commonly used as neutron absorption materials. The introduction of amorphous Al2O3 2 O 3 through surface oxidation of Al powder can significantly enhance the mechanical properties of the composites; however, the thermal stability of the composite is compromised due to the inherent instability of amorphous Al2O3. 2 O 3 . In this study, (B4C 4 C + Al2O3)/Al 2 O 3 )/Al composites were sintered in an air atmosphere with high pressure for the first time, generating stable gamma-Al2O3. 2 O 3 . It was found that in comparison with the conventional vacuum sintering process, (B4C 4 C + Al2O3)/Al 2 O 3 )/Al sintered in an air atmosphere exhibited increases in ultimate tensile strength of 42 % at room temperature and 90 % at 350 degrees C. Furthermore, due to the reaction between Al and oxygen, the composite exhibited exceptional thermal stability when subjected to annealing at 620 degrees C, demonstrating an ultimate tensile strength of 144 MPa at 350 degrees C, surpassing values reported in other studies. |
