2014 and 6061 aluminium alloy-based powder metallurgy composites containing silicon carbide particles/fibres

Comparison of Two Powder Processing Techniques on the Properties of Cu-NbC Composites

“…In these research works, Fe-TiC and Cu-Ta composites were fabricated by milling the matrix (Fe, Cu) and reinforcement (TiC, Ta) powders together and subsequently compacted and sintered. The Al-Al 2 O 3 composite was formed from Al and Al 2 O 3 powders using ECAP at 200 ∘ C. The low density of these composites was due to the difficulty in the deformation of hard reinforcement particles in the matrix during consolidation [8,9]. It was reported that the yield strength of the composite powder increased with increasing volume fraction of reinforcements [9,36].…”

“…Cold compaction or cold isostatic pressing was used as a conventional consolidation method followed by sintering [8,9]. However, these consolidation methods have a major problem which relates to a low density of the bulk material [9,10].…”

In-situ synthesis of SiC particles by the structural evolution of TiCx in Al–Si melt

“…SiC reinforced aluminum matrix composites have been applied in aerospace and automotive products since they exhibit the excellent properties, e.g. high modulus, high specific stiffness, fatigue resistance and wear resistance [5,6].…”

Preparation of nanosized silicon carbide powders by chemical vapor deposition at low temperatures

“…Therefore, SiC can be used as not only structural materials, but also optical and electronic materials. Due to the good compatibility between SiC powders and lots of metal and nonmetal oxides, SiC powders are used to reinforce metal matrix, polymer matrix and ceramic matrix composites, and display outstanding properties [3,4]. Besides, nanosized SiC powders can be used as stealth materials.…”
