“…The addition of Mo molybdenum to iron aluminide FeAl increases the cohesion strength between crystals. In addition, the addition of molybdenum leads to an increase in plastic stress, and thus an increase in ductility, and this is consistent with what other researchers have indicated [12,15]. While adding 0.3% B+ 1.5% Mo leads to an increase in the compressive strength of the Intermetallic compound material FeAl to reach (485 MPa).…”

“…They found that increasing the percentage of chromium to 5% reduced the slip wear rate from (1.6*10 -9 m 3 /m) for chromium-free samples to 3*10 -11 m 3 / m) [14]. 2013 Researchers JR Regina, JN Dupont and A.R.Marder studied the effect of adding chromium (Cr) on the mechanical properties of the compound FeAl and found that increasing the percentage of chromium increases the corrosion resistance of the compound FeAl, as it decreased from (1.75 mg/Cm 2 to 0.1 mg/Cm 2 ) when adding 5% Cr [15]. 2015 Researchers Hansol Kim,Dong Yeo,Tae Ra and Won Yong Kim studied the mechanical properties and wear resistance of the compound FeAl) after adding alloying elements to it which are zirconium Zr and molybdenum (Mo), and they found that the mechanical properties improve by increasing the proportion of both alloying elements , As for the wear resistance, it decreases with an increase in the ratio of both elements.…”

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 1*10 -9 g/ Cm, while the slip wear value of the compound FeAl without any addition was (2*10 -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 ).

This study involves fabricating Ti based materials reinforced by carbon nano-tubes. CNTs were added with weight percentage (1, 2, 3, 4 and 5 wt% ) to enhance the mechanical properties of titanium. Some properties were measured for nanocomposites (CNTs/Titanium) such as microhardness, elastic modulus, wear rate in addition to microstructure by SEM. Microhardness was increased for nano-composites, which increased 421 Kg/mm2. The results of elastic modulus shown the decreasing in elastic modulus from 124 GPa to 82 GPa for nanocomposites. Wear rate results exhibited the lower wear rate of nano-composites compared with titanium due to the filling the vacancy in microstructure by CNTs. The scanning electron microscopy images showed that uniform distribution of CNTs in titanium and the lowest defect in microstructure. The good coherence between CNTs and base metal led to good mechanical properties.
