Isothermal section of the molbdenum-iron-boron system

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