摘要	B4C/Al composites are widely utilized as neutron absorbing materials for the storage and transportation of spent nuclear fuel. In order to improve the high-temperature mechanical properties of B4C/Al composites, in-situ nano-Al2O3 was introduced utilizing oxide on Al powder surface. In this study, the Al2O3 content was adjusted by utilizing spheroid Al powder with varying diameters, thereby investigating the impact of Al2O3 content on the tensile properties of (B4C + Al2O3)/Al composites. It was found that the pinning effect of Al2O3 on the grain boundaries could hinder the recovery of dislocations and lead to dislocation accumulation at high temperature. As the result, with the increase in Al2O3 content and the decrease in grain size, the high-temperature strength of the composites increased significantly. The finest Al powder used in this investigation had a diameter of 1.4 mu m, whereas the resultant composite exhibited a maximum strength of 251 MPa at room temperature and 133 MPa at 350 degrees C, surpassing that of traditional B4C/Al composites.
