ABSTRACT
In the current study, the Iron Aluminide FeAl was prepared using powder metallurgy technology. The mechanical properties of the compound. FeAl can be improved by adding boron and molybdenum Mo. So, adding B and Mo As a result of an increase in the compressive strength of the semi-metallic compound FeAl a compressive strength of (466.5) MPa and (415) Mpa was when adding obtained (0.3% B) and 1. 5% Mo while when adding boron and, respectively, molybdenum together with ratios 0.3% B+1.5% Mo it led to an increase in the compressive, strength to 498.3 Mpa, As for the hardness test, adding 1.5% Mo increased the hardness of the semi-metallic compound FeAl to (298.3) Mpa, which was, (260) MPa for samples without any addition, and when adding 0.3% B (the hardness value became (2681) MPa), but when adding, (0.3%) B+1.5% Mo it was found that the hardness value reaches (303) MPa. As for the sliding wear test (found that the addition of was It 1.5% Mo reduces the slip wear rate of the compound FeAl to (4*10 -10 g/Cm) as well as adding, 0.3% Reduced the slip wear rate to 110 -9 g/ Cm, while the slip wear value of the compound FeAl without any addition was (210-6 g/Cmv). The addition of 0.3% B+1.5% Mo to led to a reduction in the slip wear rate g/Cm), (3.3 * 10 -11).
