“…An infrared heat lamp or freeze drying was successfully used to avoid such a drawback (6). Mechanochemical syntheses, implying high-energy milling techniques and frequently carried out under controlled atmospheres, have also been applied when complex compositions or alumina reinforced by intermetallic compounds are envisaged (33). However, these routes present some limitations for the distribution of ultra-fine second-phase particles, due to agglomeration and dispersion problems.…”

“…The Al 2 O 3 -TiC-10 wt-% ZrO 2 nanocomposites showed the best mechanical properties with flexural strength of 706 MPa and fracture toughness of 6.3 MPa m 1/2 , which was ∼20% higher than that of Al 2 O 3 -TiC. (Fe, Cr) 3 Al matrix nanocomposites reinforced by Al 2 O 3 were synthesised by mechanochemical combustion reaction induced by ball milling of Cr, Al and Fe 2 O 3 powders [269]. The mechanical properties (hardness, strength, and toughness) of cemented carbides can be increased remarkably by decreasing the grain size to sub-micron or nanometre scale.…”

“…Kim et al [11] reported the effect of Mn on the wear behaviors of Fe-20Cr matrix hardfacing alloys from 25 to 450 • C. The results indicated that γ→ε martensitic transformation was beneficial to the wear resistance of alloys when Mn content exceeded 10 wt.%. The excellent wear resistance of Fe matrix alloys could be achieved by adding hard ceramic particles, such as SiC, TiC, and Al 2 O 3 [12][13][14]. Zhang et al [15] prepared Fe-28Al-5Cr matrix composites reinforced by nano-TiC ceramic particles.…”
