Characterization of aluminium matrix composites reinforced by Al–Cu–Fe quasicrystalline particles

Microstructure and mechanical properties of an Al‐Si alloy reinforced by Al64Cu24Fe12 quasi‐crystalline particles

“…That may be caused by following reasons: 1. The b-Al 65-75 Si [13][14][15][16][17][18][19][20][21][22][23][24][25][26] Fe 3-10 phase may act as efficient dislocation pinning sites, providing addi-tional strengthening to the aluminum matrix. However this thin rod-shaped shape will destroy the continuity of metal deformation [23].…”

“…In general, the processing routes for quasi-crystalline composites are restricted to hot pressing and mechanical alloying, which are complex and costly [13,[19][20][21][22]. Further, a conventional casting route has also been employed, with lower cost and simpler process.…”

Development of Al1070-Quasicrystal (Al65Cu23Fe12) composites using friction stir processing and its mechanical characterization

“…One such technique is the strengthening of aluminium and magnesium alloys with quasicrystalline particles. These particles belongs to the category of materials which possesses quasi periodicity with crystallographic symmetries which imbibes unique physical and mechanical properties such as high strength, hardness, high elastic modulus and low coefficient of friction [10,11]. Though, the quasicrystals are invented long ago, its application as a potential reinforcement material is yet to be acclaimed.…”

Assessment of Al-Cu-Fe compound for enhanced solar absorption

“…It has the advantages of lowtemperature processing, easy control of compositions, and the production of relatively large amount of samples [14]. There are many factors affecting this process, namely, milling time, milling temperature, post milling thermal processing, and alloy composition [16,17]. There are many factors affecting this process, namely, milling time, milling temperature, post milling thermal processing, and alloy composition [16,17].…”

“…In this process, the starting powder particles (mostly elemental metals) undergo rapid fracturing and cold welding as the balls in the mill collide, trapping a small amount of powder in between causing the powder to plastically deform and leading to a continuous cycle of hardening and fracture [15]. There are many factors affecting this process, namely, milling time, milling temperature, post milling thermal processing, and alloy composition [16,17]. MA results in a significant extension of mutual solubility of the elements relative to the equilibrium values, which can be observed through X-ray diffraction patterns [18][19][20].…”
