Aluminium alloy nanocomposite made with SiC via ultrasonic stir casting: Behaviour study

The research attempted to enrich the aluminium alloy (Al/Mg) nanocomposite with silicon carbide (SiC). The ultrasonic assist stir cast established that the Al/Mgnanocomposite is involved in microstructure, hardness and tensile performance. Its result is uniform dispersion without agglomeration, and 7.5 wt% SiC owns higher microhardness and better tensile strength of 161±1.5 H V and 238±2 MPa. This nano Al/Mg alloy composite is subjected to machining studies by using a vertical CNC milling setup & titanium nitride (TiN) coated end mill functioned by 300–1200 rpm spindle speed (N), 0.01–0.04mm/rev feed rate (FR) and 0.1–0.4 mm depth of cut (DOC). The impact DOC, FR, and N on material removal rate (MRR), temperature (T), and tool wear (Tw) are measured, and the L16 design experiment (ANOVA-GLM) is defined. Finally, the best interaction input milling parameter pairs on obtaining high MRR with the least T and Tw. The DOC is the most significant factor in controlling the MRR, T and Tw.
