Design of Recycled “A356-A7075” Matrix Composites Reinforced with “Nb2Al-Zr” Produced by Sinter Forging
摘要
In this research, the mechanical properties of recycled aluminum (A356-A7075)-based composites reinforced with Nb2Al-ZrO2-TiAl have been evaluated. Different amounts of Nb2Al doped with ZrO2 were mixed with atomized recycled aluminum matrix containing “AA356-A7075” and processed by ball milling. The mixture was then sintered followed by hot forging. Static and cyclic stress relaxation compression tests and low velocity impact tests were carried out to evaluate damage behavior. Interface and microstructure of these composites were also evaluated by scanning electron microscope (SEM).
