摘要：

Fe-Cr-Ni/MgO (17.0-34.9 wt.%) composites were produced by reactive hot pressing at 600 degrees C/30 MPa/2 h. The composites comprised predominantly of Cr0.7Fe0.36Ni2.9, CrFe and MgO phases. The Fe-Cr-Ni/MgO (17.0 wt.%) composite had the optimal mechanical properties: 5.09 GPa for Vickers hardness, 412 MPa for bending strength and 11.6 MPa m(1/2) for fracture toughness, respectively.
