Many factors can influence the density uniformity of the SiC particle reinforced aluminum matrix composites, including the material preparation method and the material processing technology. The influence factors on the density uniformity of SiCp/2024Al in the extrusion process were studied in the present investigation. Those factors contain the extrusion ratio, the extrusion velocity, the temperature and the friction coefficient. The flow stress of this material under different temperatures and strain velocities was tested by heat physical simulation experiments. As a result, the true stress-strain curve was obtained and the phenomenological constitutive equation was established, and the FEM simulation was used for the extrusion process. The velocity gradient computed by the numerical simulation was used to describe the density uniformity. The density uniformity caused by different extrusion process parameters was compared and analyzed. The results showed that the density uniformity was improved obviously by the optimization of extrusion process parameters. At last, the real extrusion process test was organized to verify the numerical simulation results and the most suitable characteristic parameters of the extrusion mold and the process was finally determined.

Abstract This work focusses on the production of sustainable metal metrics composites MMCs. The scrap aluminum alloy wheel (SAAW) was used as a metrics and alumina is used as a reinforcement. The process parameters (namely squeeze pressure and time, die preheating temperature and stirrer speed) were optimized using Taguchi method to produce the alumina reinforced-aluminum matrix composites (AMCs). These stir-casted composites were characterized based on their hardness, tensile and compression strengths and wear/tribological properties. The results showed that addition of alumina to aluminum matrix has improved the mechanical and tribological performance. From, Taguchi analysis the optimized 9 approaches (L1 to L9) were obtained and, L5 and L6 methods showed optimum mechanical properties with 100 MPa squeeze pressure, 30 to 40 sec squeeze time, 250 to 350°C die preheating temperature and 450 to 525 rpm stirrer speed process parameters. It was found that properties are process parameters dependent. The produced AMCs have many potential industrial applications including applications in piping industry.

Taguchi’S Design Of Experiments

Drilling is a very important hole making process. It is very much useful for assembly of parts. Incorporation of hard ceramic particles into the matrix of metallic composites made them difficult to machine. So, it becomes inevitable to optimize the drilling parameters. The foremost objective of this research work is to fabricate Hybrid Aluminium Matrix Composites(AMCs) of LM6/B4C/Fly Ash with 3%, 6% & 9% by weight percentages of both reinforcements, equally using stir casting technique. The next objective is drilling of composites with feed, speed, drill and percentage of reinforcement as input process parameters at three levels each by Taguchi’s Design of Experiments approach. The final objective is to optimize the drilling process parameters for achieving low thrust force, low surface roughness and minimum burr height using the multi-objective Grey Relational Analysis. Results reveal that drill material plays a major role, being closely followed by feed and speed.
