“…These properties are easily achievable with the aluminium alloy based metal matrix composite (AMC) at lower costs [15][16][17][18]. The fabrication of an enhanced composite material can be done through the careful selection of proper reinforcement materials having the modulus and stiffness higher than the base metal or alloy materials [19]. Hence, the reinforcement material must have a higher strength and hardness value compared to the continuous soft ductile nature of the matrix phase.…”

Snail shells (SnS), which represent the discarded bio-shell waste of snails' remnants from restaurants and eateries constitute a serious degree of environmental threat with little or economic value. The effective utilisation of this waste into a green metal matrix composite as a low cost reinforcement material applicable in the automotive industry in lieu of its present hazardous impact had stimulated the research interest. Hence, this paper studies the potential utilisation of SnS as a low cost reinforcement material in the metal matrix composites (MMCs) by means of a characterisation technique. The mineralogical composition and physical properties of the snail shell powder was carried out using the density determination, thermogravimetric analysis (TGA), refractoriness, energy dispersive X-ray (SEM/EDX), X-ray fluorescent (XRF) and the X-ray diffraction (XRD) analysis at 0, 800, 850 and 900 C. The TGA result shows that the SnS attained its thermal stability at 840 o C. The above results imply that SnS with (9.4-25.9) % lesser density when compared with agro or industrial wastes reinforcement material (flyash, coconut shell ash, maize husk, bagasse) in the metal matrix composite looks promising as a reinforcing material in the production of light weight metal matrix composites at low costs. Also, the high refractoriness temperature of the snail shell particle suggested it as a suitable candidate reinforcement material in the production of thermal resistance MMCs applicable in automotive components such as pistons and connecting rods.

“…At room temperature, hypoeutectic alloys consist of a soft and ductile primary aluminum phase and a hard and brittle eutectic silicon phase. Hypereutectic alloys usually contain coarse, angular primary silicon particles as well as a eutectic silicon phase [3]. Many researchers have studied the modification mechanism of aluminum alloy, and it exists two modification mechanisms: TPRE (twin-plane reentrant edge growth mechanism) [4] and interfacial edge mechanism [5].…”

Abstract. The present work studies the effect of eutectic silicon particle morphology on the fluidity of 4045 aluminum alloy filler through dynamic spreading experiment, filling test and welding seam experiment. The experimental results indicate that the morphology of eutectic silicon particle has an excellent influence on the melting speed at the initial melting stage of brazing process: the alloy loaded with smaller eutectic silicon particles exhibits a faster melting speed and better fluidity. When the alloy completely melts along with those internal eutectic silicon particles in a variant morphology, particles sizes have limited impact on the fluidity. In addition, it is discovered that alloy introduced with smaller particles possesses a much lower surface activation energy; furthermore, the proportional relationship the ratio of length to diameter (S) and surface activation energy (Q) is verified in this article, and is consistent with the formula: Q=2.35S+94.47.

“…Hypereutectic alloys are characterized by eutectic matrix containing primary silicon crystals of various sizes and shapes. Low thermal expansion coefficient, high strength to weight ratio and excellent wear resistance are among the properties of these alloys, which account for their popularity as the chosen materials for automotive pistons and engine block [1][2][3][4][5][6].…”

Majority of combustion engines is produced (poured) from Al-Si alloys with low thermal expansion coefficient, so called piston silumins. Hypereutectic alloys normally contain coarse, primary angular Si particles together with eutectic Si phase. The structure and mechanical properties of these alloys are highly dependent upon cooling rate, composition, modification and heat-treatment operations. In the paper one depicts use of the ATND method (thermal-voltage-derivative analysis) and regression analysis to assessment of quality of the AlSi21CuNi alloy modified with Cu-P on stage of its preparation, in aspect of obtained mechanical properties (R 0,02 , R m , A 5 , HB). Obtained dependencies enable prediction of mechanical properties of the investigated alloy in laboratory conditions, using values of characteristic points from curves of the ATND method.
