“…Silicon carbide (SiC) and aluminium oxide (Al 2 O 3 ) nanoparticle-reinforced aluminium metal matrix composites have drawn lots of attention for their economic advantages and better performance. Many methods can be used for fabrication of Al matrix nanocomposites such as infiltration [10], squeeze casting [11], mechanical alloying [12], powder metallurgy [13], ball milling [14] and stir casting [15]. Among these methods, powder metallurgy and stir casting are the most used at present for their economic advantages and also have the most potential for mass production.…”

Ceramic nanoparticle-reinforced aluminium metal matrix composites (AMMCs) have superior mechanical properties compared with matrix alloys, exhibiting great potential in structural applications in industries such as the aerospace and automotive sectors. This research proposes a new method for distributing SiC nanoparticles in an aluminium matrix alloy by powder metallurgy. The mixing of aluminium powder and SiC nanoparticles was processed by a two-step procedure, which included ultrasound-assisted stirring and planetary agitation. After that, the mixing powder was subjected to compaction, sintering and extrusion. A blank sample and three composite sheets containing 1, 2 and 3 wt % SiC nanoparticles were prepared and the mechanical properties were investigated by micro-hardness and tensile tests. A scanning electron microscope (SEM) and electron back-scattered diffraction (EBSD) were used for microstructural analysis of the composite. Experimental results revealed that by adding 1, 2, 3 wt % SiC nanoparticles, hardness was increased by 26%, 34.5%, 40.0% and tensile strength was increased by 22.3%, 28.6% and 29.3%, respectively. The grain size of the aluminium matrix decreased with the addition of SiC nanoparticles. Moreover, a decrease of elongation was observed with the increasing weight fraction of SiC.

“…Therefore, the utilized material should provide high resistance under cyclic loadings and also high strength to weight ratio for the fuel consumption and consequently reducing the gas emission. For this purpose, the aluminum-silicon alloys are a potential candidate because of their high strength to weight ratio, good castability, acceptable ductility, and corrosion resistance [3]. There are several concepts available that could achieve improvements in mechanical and fatigue properties through the piston design including the optimized geometries, novel materials, advanced manufacturing processes, and different strengthening methods [1].…”

The objective of the present paper is to investigate the stress-controlled low-cycle fatigue behavior of piston aluminum-silicon (AlSi) alloy reinforced with nano-clay particles and T6 heat-treatment. The piston aluminum-silicon alloy strengthened by 1 wt.% nano-clay particles were prepared by the stir casting method and then subjected to the heat-treatment. The optical microscopy analysis demonstrates that heat-treatment changed the size, morphology, and distribution of silicon phases through the microstructure of the aluminum matrix. In addition to tensile tests, stress-controlled low-cycle fatigue experiments at different loading conditions including the variation of the mean stress, the stress rate, and the stress amplitude were conducted at room temperature. The obtained experimental results showed no clear improvement in either mechanical or fatigue properties of the material. Moreover, the density measurements using the Archimedes method reveal a higher content of the porosity in nano-composite. It was observed that the reinforcement (nano-particles and heat-treatment) can change the cyclic behavior of the AlSi alloy, significantly. The cyclic hardening feature of the AlSi alloy changed to cyclic softening and also the fatigue lifetime and the ratcheting resistance decreased after the nano-particles addition and heat-treatment. Through the microstructural analysis, it was indicated that the neglecting of higher kinematics of age hardening in nano-composite was the major source of mechanical properties reduction. In the end, it was shown that the fatigue lifetime of samples can be described adequately utilizing a modified plastic strain energy technique considering the mean stress effect.

The current research paper discusses the characterization and machining (turning) operation of aluminium (Al) and silicon carbide nano particle (SiCp) nano composite. The paper reveals proper distribution of silicon carbide nano particles (25nm) with aluminium metal matrix. Initially, tensile test has been carried on metal matrix nano composite to study its different properties. It was noticed that the properties of Al-SiCp increases by increasing the weight percentage of SiCp. Viker hardness test has also been conducted to find out the hardness of metal matrix nano composites. Different techniques i.e. Optical microscopy EDX-Analysis were utilized to find out various ingredients of the nano-composite material. The experimental study was carried out using Taguchi L 16 orthogonal array by taking three different factors at four different levels each. The response parameters i.e. flank wear of coated carbide insert and surface roughness of Al-SiCp has been optimized by using Principal Component Analysis (PCA). Various graphs like main effect plot and normal probability plot have been plotted and studied properly. Different optical images of coated insert carbide tools (Insert CNMG 12040822TN 6010) at different runs were conducted to visualize the effects of process and response parameters. From the ANOVA table, it was found that cutting speed as well as depth of cut are found to the most vital parameters in influencing the responses for VBc and depth of cut and feed are found to the most significant parameters in influencing the responses for Ra.
