“…Subsequently the movement and arrangement of dislocation forms lot of small angle grain-boundaries refining initial grains into several substructure. In addition to the refinement of grains, hot deformation also promotes homogeneous precipitation hardening of 'θ' and Q-phases which can pin the movement of dislocations to restrain grain coarsening during re-crystallization effectively [11] . No significant difference is observed in the other microstructural features such as the aspect ratio and distribution of brittle 'β' particles.…”

The hypereutectic Al-Si alloys with alloying elements such as Mg, Cu, Fe and Mn have been successfully produced by modern processing technologies to improve strength to weight ratio, mechanical properties and wear behavior at elevated temperature [1]. Alloying of Al with high content of Mg and Si results in the formation of Mg 2 Si phase and eutectic Al-Mg-Si phase. Offers the possibility of significant decrease in density (density of Mg 2 Si-1.99 gcm-3) and increase in stiffness compared to other Al alloys and makes them superior material for the light weight automotive applications [2]. However, the slow cooling rate of the melt associated with conventional casting methods results in a coarse microstructure of primary phase and formation of large intermetallic phases with a high degree of micro-macro segregation. Al alloy with high content of Mg 2 Si poses several difficulties by conventional casting processes due to excessive slag formation and generation of porosity caused by high solubility of hydrogen

“…This is portrayed at a load of 40 N , the wear rate started to decline gradually but a steep increase is noted at a load of 50 N with the different constant sliding velocity. This also witnessed deterioration in the friction coefficient with increase in load (Godar et al , 2013; Corrochano et al , 2011). The wear rate is amplified with the speed when tested with varying constant loads (Abouei et al , 2010).…”

PurposeAluminium is the most proficiently and commonly used metal due to its desirable physical, chemical and mechanical properties. When Aluminium reinforced with hard ceramic particles, shows increased strength and good corrosion resistant and wear resistant qualities. In the present investigation, A390 + X vol. % Zro2 (X = 5, 10 and 15) composites have been fabricated through P/M technique.Design/methodology/approachAfter that the microstructural properties are tested by scanning electron microscope (SEM) analysis wear test is performed using pin-on-disc machine.FindingsThe wear conditions of applied load 30N and sliding velocity 1 m/s and track distance 1000m was followed. A390 + 15% Zro2 of surface of the composites unveiled greater hardness when compared with A390 alloy.Originality/valueA390 + 15% Zro2 exhibited superior wear resistance than that of the matrix alloy. Thus the material proves as an excellent solution for applications that requires high wear resistance.

“…To further enhance the wear resistance at elevated temperature and thermal stability of the hypereutectic Al-Si alloys, alloying elements for instance Fe, Ni, Mg, Cu, Mg, Mn and Zn are added. Alloying these elements into Al-Si results in the formation of hard primary Si and inter-metallic phases that increase the wear resistance of the Al-Si alloy [7]. Zinc has higher solubility in aluminium alloy compared to the other alloying elements and improves hardness of the aluminium matrix.…”

The tribological characteristics of stir cast Al-15%Si-10%Zn matrix with 15%ZrO 2 reinforced composite were investigated. The microstructure of the Al-15Si alloy consisted of coarse primary Si and acicular eutectic Si phases randomly distributed in the Al dendrites. The Al-15%Si-10%Zn/ZrO2 composite showed spherical Si with a size between 25 and 75 µm; fragmented eutectic Si phase and uniform dispersion of ZrO 2 particles in the matrix. The wear test was conducted using in a pin-on-disc method at different loads and sliding velocities. It was found reduced coefficient of friction, significant increase in the hardness and wear resistance of the composite compared to the matrix alloy. High wear resistance in the composite due to the effect of solid lubrication provided by Zn, and good fracture toughness and wear resistance by the reinforced ZrO 2 particles. The predominant oxidative and abrasive wear were identified as the mechanisms leading to material failure through plastic deformation and delamination.
