Aluminum is a material with advantageous properties such as lightness, good conductivity, high plastic deformation ability, and superior corrosion resistance. However, aluminum and many aluminum alloys have disadvantages in terms of mechanical properties such as hardness, tensile strength, and wear resistance. To overcome this disadvantage of aluminum, it is a good method to add ceramic particles to the matrix. For this purpose, in this study, B4C (boron carbide)-reinforced AA2014 aluminum matrix composites were fabricated at 3%, 5%, and 7% reinforcement ratios using the stir casting method. Tensile tests, wear tests, cutting force measurements, and microhardness measurements were performed to determine the fabricated composite materials’ mechanical properties. Scanning electron microscopy and optical microscopy were used to analyze the microstructure of composite. X-ray diffraction analysis was utilized to study the phase identification. As a result of the study, it was observed that with the increase in the B4C reinforcement ratio, the mechanical properties of the aluminum matrix composite material, such as wear resistance, cutting strength, and hardness, increased. On the other hand, the change in tensile strength did not occur in this way. Tensile strength first increased and then decreased. The highest value of tensile strength was achieved at 5% B4C reinforcement. X-ray diffraction results showed that AA2014 and B4C were the fundamental elements in composites and are free from intermetallics.

The stringent demand to develop lightweight materials with enhanced properties suitable for various engineering applications is the focus of this research work. Industrial wastes such as fly ash (FA) and S-glass-fibres (GF) were used as reinforcement materials for high-strength alloy, i.e., Al 7005. Stir casting routes were employed for fabricating the four samples, Al 7005, Al 7005 + 5% GF, Al 7005 + 6% FA and Al 7005 + 5% GF + 6% FA. The extrusion process with different extrusion ratios (ER: 5.32:1, and 2.66:1) was used to examine the properties of all four samples. Extruded samples with ER: 5.32: 1 resulted in equiaxed grains with refined structure compared to stir casting parts. The effect of the extrusion process and the addition of reinforcements (GF and FA) on the gravimetric, electrochemical, and electrochemical impedance corrosion behaviour of Al 7005 composites in 1M HCl (Hydrochloric acid) solution were investigated. The results of all three corrosion methods showed that Al 7005 + 6% FA exhibited higher corrosion resistance. Corrosion rate of Al 7005, Al 7005 + 5% GF, Al 7005 + 6% FA and Al 7005 + 5% GF + 6% FA is found equal to 3.25, 2.41, 0.34, and 0.76 mpy, respectively. The FA particles remain inert and act as a physical barrier with corrosive media during the corrosion test. GF undergoes fibre degradation or disrupts the continuity of the glass network as a result of fibre leaching, which increases the corrosion rate in the sample. The gravimetric study showed that the corrosion rates decreased with an increase in extrusion ratio, which might be due to corrosion passivation increases and improved properties. The scanning electron microscopy reveals that corrosion fits, flakes and micro-cracks were observed more in the as-cast composites than that of extrusion composites, promoting the corrosion rate.

“…This has already been extensively investigated in many studies for different metallic materials: for mild steel in [11,13,18], for various dual-phase steels in [10][11][12] and also for stainless steel and TRIP steel in [11,14]. Temperature and strain-rate effects, which influence the material behaviour at high-rate loads similar as at low-rate loads [19], are considered in this material model through empirical parameters in the J-C equation [4]. Their appropriate values can be applied in numerical simulations to obtain more accurate physical reactions for a product under different loading conditions during its R&D process.…”

Under conditions where a product is subjected to extreme mechanical loading over a very short time period, the strain rate has considerable influence on the behaviour of the product’s material. To simulate the behaviour of the material accurately under these loading conditions, the appropriate strain-rate parameters for the selected material model should be used. The aim of this paper is to present a quick method for easily determining the appropriate strain-rate-dependent parameter values of the selected material model. The optimisation procedure described in the article combines the design-of-experiment (DoE) technique, finite-element simulations, modelling a response surface and an evolutionary algorithm. First, a non-standard dynamic experiment was designed to study the behaviour of thin, flat, metal sheets during an impact. The experimental data from this dynamic and the conventional tensile experiments for mild steel were the basis for the determination of the Johnson-Cook material model parameters. The paper provides a comparison of two optimisation processes with different DoE techniques and with three different optimisation algorithms (one traditional and two metaheuristic). The performances of the presented method are compared, and the engineering applicability of the results is discussed. The identified parameter values, which were estimated with the presented procedure, are very similar to those from the literature. The paper shows how the application of a properly designed plan of simulations can significantly reduce the simulation time, with only a minor influence on the estimated parameters. Furthermore, it can be concluded that in some cases the traditional optimisation method is as good as the two metaheuristic methods. Finally, it was proven that experiments with different strain rates must be carried out when estimating the corresponding material parameters.
