摘要

Aluminium based metal matrix composites had drawn most attraction because of enhanced properties in structural applications for the past two decades ; therefore fatigue and tensile properties of composite materials should be studied for their structural applications .In the present research nanoparticles TiO2 were added with different weight percentage (l,3,5,7,and 9wt.%) and average particles size (10-20nm) to the 7075/T6 Al -alloy by stir casting technique. The results indicated that the tensile and fatigue properties increase with increasing the wt. % of TiO2 nanoparticle. The optical micrographs of 7075 Al- alloy with l,3,5,7,and 9wt.%) TiO2 particles were shown uniform distribution of TiO2 and less level of porosity of microstructure compared to 7075/T6 Al-alloy and the optimum improvement in tensile and fatigue properties is occurred at 9 wt.% of TiO2.
