摘要: Abstract In the present study, SiC particle reinforced molybdenum–disilicide (MoSi 2 ) matrix composites have been fabricated by hot press sintering and in situ reaction process successfully. Hot pressed SiCp/MoSi composite has a phase constituent with about 20 vol.% α -SiC less Mo 5 Si 3 MoSi matrix. SiC/MoSi contains 24.5 β small amount of Two types improved their hardness, flexural strength fracture toughness. Compressive yield at 1200 1400°C also enhanced obviously. Wear behavior test abraded on Al O grind wheel shown very excellent wear resistance compared monolithic .
