“…Aluminum alloys are commonly used in the automotive and aerospace industries due to their favorable properties, such as a high strength-to-weight ratio, ease of fabrication, good thermal conductivity, and good corrosion resistance [1][2][3][4]. Among these alloys, aluminum-silicon alloys are commonly used to manufacture combustion engine components, such as pistons and cylinder heads, which typically operate at elevated temperatures [5,6].…”

“…During the experimental investigation, the temperature and total strain of the material are kept constant while the stress gradually decreases over time. Under the action of time, the elastic strain inside the material gradually transforms into the process of plastic strain [4]. During the relaxation test, stress reduction is measured as a function of time.…”

Al–Cu–Mg alloys are widely used in various applications, especially engine components, where it is subjected to elevated temperatures during operation. Prolonged exposure of these components to elevated temperatures gradually leads to creep and relaxation phenomena. This study aims to investigate the effects of temperature on stress relaxation and creep behavior of the aluminum-silicon alloy EN AC-Al Si12CuNiMg. Furthermore, this study evaluates the effect of temperature on the rheological model parameters of this alloy. Experimental tests were conducted to investigate the stress relaxation and creep behavior of this alloy at different temperatures of 150°C, 250°C, and 350°C. The rheological model parameters were then determined from the obtained experimental data. The Standard Linear Solid Model (SLSM) was used to fit the stress relaxation and creep curves obtained from the experiment. Overall, the results indicate that increasing temperature significantly affects the stress relaxation and creep behavior of the investigated alloy, with higher temperatures leading to increased relaxation and creep rates. Additionally, the rheological model parameters of the alloy were found to vary with temperature.

“…The aluminium matrix composites (AMCs) have been developed by various processing techniques. Among these routes, stir casting is the proved auspicious techniques for producing AMCs because of their easiness, suppleness, inexpensive and appropriate to large quantity fabrication [14,15]. Poppy Puspitasari et al [16] studied the mechanical properties in Al-Si alloy with the presence of ZnO particles and reported that by adding ZnO, the strength and hardness of the composite have been improved.…”

This work aims to apply data-driven approach [decision tree (DT) algorithm] to analyse the wear rate (WR) of ZnO-filled AA7075 composites. The results of model-based analysis was compared with Taguchi analysis. Stir casting was used to produce the composite samples. Characterization studies were conducted to analyse the composition and morphology. The scanning electron microscopy results indicated the even dispersion of ZnO in the AA7075. The energy-dispersive x-ray spectroscopy pattern ensures the presence of matrix elements and the inclusion of reinforcement particles into the proposed composites. To minimize the number of experimentation, L27 Orthogonal array is used for finding WR. The 'DuCom' Pin-on-Disc apparatus were used to prepare WR data for the set of the proposed composites. Taguchi technique reveals the optimum level factors for obtaining the minimum 'WR' is reinforcement content of 10 wt.%, applied load (P) at 10 N, sliding velocity (V) at 1 m s −1 and sliding distance (D) of 1000 m. The experiments results from DT algorithm, and analysis of variance and signal-to-noise ratio analysis from Taguchi-based approach confirmed that reinforcement is the primary element for affecting wear of the composites. The reason for applying DT algorithm is that, the low-level knowledge could be converted into high-level knowledge (If-then-else rules), which can be effortlessly explicable by semiskilled personnel.
