Development in mechanical and fatigue properties of AA6061/AL2O3 nanocomposites under stirring temperature (ST)

Aluminum is expected to remain the core material for many critical applications such as aircraft and automobiles. This due high resistance different environmental conditions, desired manageable mechanical properties, well fatigue resistance. nanocomposites AA6061/Al2O3 can be made in ways using a liquid metallurgy method. The main challenges this method production of are difficulties achieving uniform distribution reinforcing materials possible chemical reactions between matrix. For structural exclusive aerospace sectors. growing cost-effective mass technology with essential operational geometric flexibility big challenge all time. Each preparing provide properties. In present study, nine were prepared at three stirring temperatures (800, 850, 900 °C) level Al2O3 addition 0, 5, 7, 9 wt %. results tensile, hardness tests revealed that composite including % 850 °C has best It was also temperature (ST) an increase tensile strength, VHN reduction ductility by 20 %, 16 36.8 respectively, compared zero-nano. Also, life 90 MPa stress increased 17.4 comparison nanocomposite 800 (ST). Uniform distributions observed microstructure compositions.
