Microstructure and properties in Al–C–Cu system produced by mechanical milling

Characterization of Al–Al4C3 nanocomposites produced by mechanical milling

“…During the sintering treatment finely Al 4 C 3 particles dispersion are produced insitu which are responsible for improving the resistance even at high temperature [6]. In some cases, the graphite dispersion from the mechanical alloy reinforces the material at low temperatures, while at high temperatures, the composites are held by dispersion of Al 4 C 3 particles formed during the sintering [7]. It is evident that one of the most important properties of the Al 4 C 3 used as reinforcing material in nanocomposites is their high temperature strength [8][9][10].…”

Microstructure and electrical resistivity features in Al-Al4C3 in-situ composite after attrition milling and double sequence of compaction and high temperature treatment

“…Recent researches reveal that addition of fine oxides and carbides can contribute to high temperature strength together with advanced toughness, fatigue and corrosion properties [16]. Some preliminary studies were concentrated on in-situ Al composites reinforced by fine Al 4 C 3 and Al 2 O 3 precipitates, where results reveal these particles have considerable effects on optimum mechanical properties of the materials [17][18][19][20][21][22][23][24][25]. In several alloy systems, synthesizing of these stable precipitates through MA process is gaining interest in the last decade.…”
