“…So DRX nucleation first appears around the reinforced particles. However, the interfacial migration and interface formation are hindered by the pinning of particles, which means, the growth of recrystallization grains is hindered, which is consistent with the research [15,30,31] of Xu el. and the grain distribution shown in the figure 6(d).…”

“…In the study about the hot deformation behavior of the metal or metal matrix composites, Arrhenius constitutive model describes the relationship between flow stress(σ), strain rate(ε) and temperature(T) [15]. It is assured that equations (2)) are applied to lower stress (ασ<0.8) and higher stress (ασ>1.2) respectively.…”

“…F. Khodabakhshi et al [14] found out the main mechanism of aluminum-matrix hybrid nanocomposite at high temperature deformation was DRX. Chen et al [15] prepared the micro-SiC and nano-TiB 2 reinforced aluminum matrix composite and found that the major softening mechanism was DRV. Meanwhile, they claimed that the reinforced particles provided power for partial DRX.…”

The hot deformation tests of in situ ZrB 2 and Al 2 O 3 nanoparticles reinforced AA6016 matrix composite were studied at deformation temperature of 300°C-450°C and strain rate of 0.001-1 s −1 . In this paper, the ZrB 2 and Al 2 O 3 nanoparticles were successfully prepared by direct melt reaction method firstly. Based on experimental results, the flow stress increased rapidly with the increasing true strain and decreased with the increasing temperature. Constitutive equation of the composite can be established based on the Arrhenius constitutive model. The processing map based on dynamic material model showed two stable processable domains: Domain A(300-360°C/0.08-0.01 s −1 ), which was controlled by dynamic recovery and domain B(410-430°C/0.37-1 s −1 ), which was typical dynamic recrystallization structure. The microstructural changes of the samples after deformed were observed through optical microscope (OM), scanning electron microscope (SEM) and transmission electron microscope (TEM). It was concluded that these two kinds of reinforced particles can greatly promote recrystallization nucleation at high temperatures. Thus, domain B is optimum hot processing window.

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.

Abstract: Aluminium Metal Matrix composition were used in application of the aerospace and automobiles because of its strength and stiffness. Although tribological characteristics of the materials like wear resistance is low. Many research has been carried out in the particle reinforcement with the Aluminium Metal Matrix. In this paper, the several reinforced particles with the aluminium matrix were reviewed. The reinforced materials like Tungsten carbide, graphite or hybrid reinforced materials were analyzed. The stir casting process is the common technique to fabricate these materials. The reinforcement of graphite particles in aluminium materials were shows the considerable mechanical properties.
