Summary

  1. 1.

    The Mo-Fe-B system has been studied by x-ray structural methods and microstructural analyses, and the isothermal cross section at 1000‡C has been constructed.

     
  2. 2.

    It has been found that the ternary phase (Mo, Fe)3B2 has a crystal structure which is superstructural with respect to the U3Si2 type (for the composition Mo2FeB2 a=5.807±0.004 A, c=3.142±0.003 A).

     
  3. 3.

    For the composition MoFe2B4 the existence has been confirmed of a compound with a structure which is superstructural with respect to the Ta3B4 type, and the lattice constants have been determined (a=3.128±0.005 A, b=12.70±0.01 A, c=2.984±0.005 A).

     
  4. 4.

    Iron has a stabilizing effect on the high-temperature modification of MoB.
