摘要：

In this study, Mo0.9Cr0.1AlB solid solution ceramic bulks were prepared from the element powder mixtures using hot pressing sintering method. Compared with MoAlB ceramics, the grains of as-prepared Mo0.9Cr0.1AlB were refined obviously. The lattice constants of Mo0.9Cr0.1AlB were confirmed to be a = 3.205 A, b = 13.999 A and c = 3.098 A. The density of Mo0.9Cr0.1AlB was lower than that of MoAlB due to the incorporation of Cr element. In addition, the effect of doping Cr element on the comprehensive mechanical properties was studied as well. The hardness and compressive strength were improved significantly. In comparison with MoAlB ceramic, the improvement of mechanical properties could be attributed to solid solution strengthening and grain refinement.
