摘要：

Fully dense composites of Zr-3[Al(Si)](4)C-6 were prepared by reactive hot-pressing. The composites were prepared from ZrH2, Al, Si, C and B4C and contained 10-30 vol% ZrB2+ZrC in a 2-to-1 M ratio. As reinforcing agents, ZrB2 and ZrC exhibited strengthening and toughening effects to the Zr3[Al(Si)]4C6 matrix. The bending strength was 625 MPa, the fracture toughness was 7.2 MPa m(1/2), and the Vickers' hardness was 16.4 GPa. (C) 2013 Elsevier B.V. All rights reserved.
