Abstract
The goal of the present work is to study the effect of different sintering temperatures (900, 1000 and 1100 ) on fatigue and mechanical characteristics of the metal matrix AA5052 reinforced with 5% of TiO₂ nanoparticles. The stir casting process is used for manufacturing of AA5052/TiO₂nanocomposite. The mechanical characteristics of nano composites have been obtained at ambient temperature. The results of mechanical properties showed that the best enhancement in hardness (HB), ultimate tensile strength (UTS) and yield strength (YS) is occurred in nanocomposite with 1000 sintering temperature (ST). However, the fatigue test results showed that the samples manufactured under 1000 (ST) have longer fatigue life compared to other materials with different sintering temperatures. The endurance fatigue strength is improved by 7.2% compared to metal matrix. The experimental results showed that the microstructure image of 1000 (ST) composite has uniformly distributed of TiO₂ in AA5052 matrix.
Highlights
TiO₂ particles reinforced AA5052 composites are successfully fabricated by the stir casting route. The effect of different sintering temperatures (900, 1000 and 1100℃) on fatigue and mechanical characteristics of the metal matrix AA5052 reinforced with 5% of TiO2 nanoparticles was studied. Compared to other sintering temperatures, the nanocomposite with a sintering temperature of 1000℃ has the highest hardness, ultimate tensile strength, yield strength and the lowest elongation.
