“…More details of these microstructures including FE-SEM images were found in previous studies [1,3]. Azadi et al [17,38] and Shari et al [53] showed that by the presence of the reinforcement (nano-particles plus the heat treatment), the change in the Si morphology was signi cant and seemed to be the needle-shape and also the block shape. Due to the reinforcement, the Si phase percentage enhanced as 8%.…”

“…Then, to reinforce the material, nano-clay particles (type: montmorillonite K10) were used in the aluminum-matrix. The weight percent of nano-clay particles was considered as 1% based on the literature [17,38]. Moreover, the chemical composition of nano-clay particles shows in Table 2.…”

“…To fabricate initial materials, nano-clay particles were rstly pre-heated at 400℃ [39] and then, were added into the aluminum melt by the stir, with the amount of 2 gr. This work was done to have a better melt quality and also to eliminate any gas accumulations in the aluminum melt [17,40]. The fabrication technique for the piston aluminum-silicon alloy for fatigue testing was the gravity casting approach.…”

“…In following paragraphs, a literature review could be seen for fatigue properties of aluminum alloys [4][5][6][7][8][9][10][11][12][13] and aluminum-matrix composites [14][15][16][17]. In addition, some other articles [18][19][20][21][22][23][24][25][26][27][28][29][30][31][32][33][34][35][36][37] have been reviewed for corrosion-fatigue properties of aluminum alloys.…”

“…They revealed that based on the stress-lifetime curve, the nano-composite fatigue behavior was better than that in the base material. Azadi et al [17] studied low-cycle fatigue properties at elevated temperatures in piston aluminum alloys, both with and without reinforcements, the heat treatment nano-clay particles. They obtained that the reinforcement in uence was not signi cant on the low-temperature fatigue lifetime.…”

In this research, the corrosion effect has been investigated on the high-cycle fatigue lifetime and the fracture behavior for the heat-treated aluminum-matrix nano-clay-composite and piston aluminum alloys. For this objective, after fabricating stir-casted nano-clay-composite, standard samples were machined and rotary bending fatigue tests were performed. To study the corrosion effect, some specimens were corroded in in the 0.00235% H 2 SO 4 solution after 200 hours and then, they were tested under cyclic bending loading. Due to increase in the hardness by adding nano-clay particles and the heat treatment, higher fatigue strength occurred, compared to the base material. Nano-clay particles shortened the fatigue lifetime; however, this effect was less in the corrosion-fatigue lifetime. Moreover, the failure mechanism was the brittle fracture behavior due to the observation of quasi-cleavage and cleavage marks.

Aluminum‐silicon alloys have been widely used in automotive industries. To know mechanical properties of such materials is essential for engineers to have a superior design for components. Therefore, in this article, the sensitivity analysis of mechanical and fracture features in the aluminum alloy has been performed to find the effect of the loading rate and nano‐particles. For this objective, tensile tests were performed on casting standard specimens. Then, obtained experimental data were analyzed by the Minitab software, using the factorial method. In addition, the interaction between the effect of the loading rate and the addition of nano‐particles, on mechanical properties and ductile/brittle behaviors, was also investigated. Obtained results indicated that the yield stress, the elastic modulus and the elongation were sensitive to the interaction of both factors (the multiply of the nano‐particle addition and the loading rate). Besides, the fracture surface illustrated that by increasing the loading rate and the addition of nano‐particles, the brittleness of the material increased.
