“…Mg 2 Si intermetallics are suitable reinforcements for aluminum and magnesium alloys because of their superior characteristics. In particular, aluminum or magnesium composite alloys with Mg 2 Si dispersoids fabricated by powder metallurgy or in-situ casting process show high mechanical properties and a good wear resistance due to the uniform distribution of fine Mg 2 Si particles in the matrix [78,[282][283][284][285].…”

Background: Improvement of the mechanical and tribological properties due to extrusion can be attributed to the improved density and excellent bond strength due to high compressive stress. Methods: To avoid the product defects mathematically contoured cosine profiled die was used for the thermomechanical treatment. Improvement of mechanical characterization like density, hardness, compression test and three-point-bend test was inquired. Two body dry sliding wear behaviour of the prepared AMCs before and after extrusion were investigated by using a pin-on-disc wear testing method by varying the variable parameters like load (N), track diameter (mm) and RPM of the counter disc. Results: The effect of hot extrusion on mechanical and tribological characteristics of aluminium matrix composites (AMCs) developed by powder metallurgy route followed by double axial cold compaction and controlled atmospheric sintering was studied. Conclusion: Shearing of the fine distributed graphite particles at the tribosurface acts as a solid lubricant and decreases wear rate. At higher loading and sliding velocity condition a mixed type of wear mechanism was observed.

“…In-situ metal matrix composites in which reinforcement is generated within the alloy offers an advantage of clean interface with minimal interfacial reaction between reinforcement and matrix [4] [5]. Amongst many types of reinforcements used [3,[6][7][8][9][10][11][12][13], TiB 2 reinforcement in aluminium alloys using salt based insitu methods offers great advantages such as minimal reactivity [7], clean interface [14], sound thermal conductivity [15] and high elastic modulus and hardness [16]. TiB 2 particles acts as a heterogeneous nucleating site for α-Al [11] controlling the grain size, thereby improves the mechanical properties of the Al matrix.…”

M A N U S C R I P T A C C E P T E D ACCEPTED MANUSCRIPT Abstract:The present work deals with the effect of semisolid processing on microstructure and mechanical properties of Al-4.5 % Cu -5% TiB 2 in-situ cast composites. The composite was prepared by flux assisted synthesis in which TiB 2 particles were formed in-situ through an exothermic reaction between K 2 TiF 6 and KBF 4 halide salts. Al-4.5wt% Cu alloy and Al-4.5%Cu-5 % TiB 2 composite samples were forged in semisolid state with 0.3 volume fraction of liquid. Semisolid forging was carried out for two forge reductions (30% and 50% forge reductions). Microstructure studies show that the semi-solid forging results in uniform distribution of TiB 2 particles and Al 2 Cu particles in the composite. Further, TiB 2 particles play a dual role as grain refiners as well as reinforcements of composites. EBSD and nano indentation studies shows that semisolid forging results in dynamic recrystallization of grains in the composite with significant grain refinement which leads to a marked increase in hardness and elastic modulus of the alloy as well as the composite.
