“…Finally, Figures 9-11 show the radial strain rate, tangential strain rate, and equiv creep strain obtained from both analytical and numerical solutions for the three rotat speeds 300, 500, and 1000 rad/sec, respectively. Again, all results shown are in full agreem with similar published data and display excellent compliance and high accuracy betw analytical and numerical solutions [26][27][28][29][40][41][42][43].…”

“…It is observed through empirical findings that creep during uniaxial loading can be reduced through the combination of aluminum alloys reinforced with ceramics, i.e., silicon carbide (Si-C) in comparison with pure aluminum [25][26][27][28]. It may impart considerable strength to composites (combination of aluminum alloys with ceramics) [29][30][31]. Ziaei et al [32] examined the stress redistribution along with creep in a thick-walled cylinder composed of functionally graded material (FGM) subjected to heat flux and mechanical loading through the Baily Norton model.…”

Creep analysis is crucial when dealing with thick rotating cylinders exposed to a steady load or stress at a higher temperature. These cylinders present a fundamental constituent in a variety of dynamic engineering applications, such as pressure vessels, hydraulic cylinders, gun barrels, boilers, fuel tanks, aerospace technologies, nuclear reactors, and military equipment. Thus, severe mechanical and thermal loads cause significant creep and reduce service life. Hence, the prediction of creep in such axisymmetric components, including pressure vessels, subjected to steady load at elevated temperatures is extremely important and quite a complex task. Thus, in this study, the creep behavior in a rotating thick-walled cylinder made of Al-SiCp composite subjected to constant load as well as internal and external pressures is investigated, both analytically and numerically, using FEM. A wide range of rotational speeds effect on the process is also included. The creep behavior is assumed to follow the Norton constitutive model, and for stress failure analysis, von Mises yield criteria are adopted. The effect of internal and external pressures, as well as the rotational speed on the stresses, strains, and strain rates in the cylinder, is studied and presented. Both finite element analysis (FEA) and Lame’s theory were used to determine the radial, tangential, and longitudinal displacements and corresponding stresses, as well as the equivalent Von Mises stresses and strain rate distributions in the cylinder revolving about its own axis. It is observed that with the increase of the internal pressure in the cylinder, the strain rate increases. Meanwhile, when subjecting the cylinder to both external and internal pressures, the strain rates tend to decrease. For instance, it was also found that stress and strain rates were higher for the 1000 rad/sec rotational speed of thick cylinder in comparison with lower rotational speeds of 300 and 500 rad/sec. Also, it is noticed that the variation in these values at the inner radius was more than those found at the outer radius. All results of the stresses, strains, and strain rate distributions obtained are found to be in full agreement with the published data. Furthermore, all plotted results of the stresses, strains, and strain rate distributions obtained through the analytical approach were found to be in exceptional compliance with those solutions obtained using finite element analysis (FEA).

“…MMCs have attracted considerable interest for applications in the aerospace and automotive industries due to their superior mechanical and thermal performance 5,6 . Aluminium-based silicon carbide (AlSiC) composites are one of the most important MMCs [7][8][9] , where the aluminium alloys act as the matrix component and the SiC particles play the role of the reinforcing component. As research continues, AlSiC composites have been found to be useful in various industries, including aerospace, biomedical, underwater, automobile, and electronics [10][11][12][13] .…”

Aluminum-based silicon carbide (AlSiC) composites with high thermal conductivity were fabricated by post-oxidization of reaction-bonded silicon carbide (RBSiC) preforms in conjunction with vacuum pressure infiltration technology. The study investigated the control of interfacial reactions in conventional sintering and reaction sintering regimes. Conventional sintering introduced a large amount of SiO2, which was detrimental to the thermal conductivity of the AlSiC composite. In contrast, reaction sintering generated β-SiC, which improved the thermal and mechanical properties. An additional post-oxidization process was proposed and applied to the RBSiC preforms to decontaminate the particle interface and prevent the generation of Al4C3. The XRD analysis revealed that the AlSiC composite treated with post-oxidization did not show an Al4C3 signal. Notably, the thermal conductivity of the sample treated with post-oxidization increased by 6.5% compared to the sample that was not treated. The study also analyzed the impact of particle size distribution on volume fraction and thermal properties. The final results showed that the thermal conductivity, coefficient of thermal expansion, bending strength, and bending modulus of AlSiC composites were 237.3 W/m·K, 8.5×10-6/°C, 325 MPa, and 75.9 GPa, respectively.
