“…As it could be seen, the slope of curves was similar and no significant change could be observed by reinforcing the base material. Raju et al 14 reported such a behavior, when nano-Al 2 O 3 -particles were added to the aluminum alloy. However, as a general conclusion, the improvement of the fatigue lifetime by reinforcing in this article had an agreement with the literature.…”

“…In this field of study, including high-cycle fatigue (HCF) and lowcycle fatigue (LCF) properties of aluminum-silicon alloys, a literature review has been done in following sentences. For such objective, the first group of articles 2,[6][7][8][9][10][11][12][13] is about the heat treatment effect and the second one of researches [14][15][16][17][18] is related to the addition of nano-particles or nano-tubes.…”

In the present article, a heat-treated nano-clay-composite was fabricated by stir-casting to improve high-cycle bending fatigue properties of AlSiCu aluminum alloys, which have been widely used in engine cylinder-heads. For such an objective, after ball milling of nano-clay-particles with micro-copper-particles, these coated particles were added to the aluminum melt and cylindrical specimens were stir-casted. Then, fully-reversed stress-controlled fatigue testing was performed on standard samples. In addition, the fracture surface was examined by the field-emission scanning electron microscopy to find failure mechanisms. Obtained results showed that reinforcements, including nano-clay-particles and the heat treatment increased the fatigue lifetime, at least 9%. Such an improvement in the fatigue lifetime was 125% under low values of the stress level. Due to have a proper distribution of nano-particles in the aluminum matrix, the scatter-band for the fatigue lifetime was narrower in the heat-treated nano-composite. The endurance fatigue limit was also improved 30% at 106 cycles, for the heat-treated nano-composite, comparing to the base material. The brittle fracture was observed due to have cleavage and quasi-cleavage marks on the fracture surface for both materials. Micro-cracks were initiated and propagated from Si and intermetallics phases.

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.
