Molybdenum silicides alloys with different Mo and Cr additions were produced by the arc cast method. The microstructure revealed mostly single phase structure. Mechanical properties were evaluated in the alloys, showing a decreasing behavior on microhardness. Fracture toughness values were obtained from cracks produced by Vickers indentation technique, showing that ternary alloying did not have a significant effect. Vacancy studies demonstrated that thermal vacancies along the transition line slightly affected the mechanical behavior.
