Toughening Mechanism of Recycled “AA7075-NanoA1050” Based Composites Reinforced with Boron Carbide (B4C) and NiAl Through Combining Method; “Sintering + Forging”
摘要
In this study, the microstructural evolution and static/dynamic compression behaviour of recycled mixture of AA7075-Nano A1050 matrix composites reinforced with boron carbide (B4C) was studied. It is aimed to be an alternative to traditional alloys/composites used in the aeronautic industry. These composites are generally produced using by combined sinter + forging processes. The static and dynamic properties were evaluated in detail, taking into account the relevant Scanning Electron Microscopy (SEM) microstructures. Simulation of the static compression test were compared with experimental results Time depending experimental study were also carried out. Cyclic stress relaxation tests were also carried out for optimization.
