Abstract:Be-Al alloy is a type of in situ metal matrix composite composed of a primary Be phase for strength and stiffness and a continuous Al matrix for ductility and toughness. Be-Al alloy (AlBe-Cast®910) has the characteristics of low density (2.17 g/cm3), high elastic modulus (193 GPa) and specific stiffness (88.94 GPa/(g/cm3)) as a preferred material for lightweight aerospace products. Investment casting technology can be employed to prepare the components with thin-walled complex structures for aerospace; however… Show more
“…The Be-Al alloy is the preferred material for use in lightweight aerospace products. Li et al [9] firstly introduced the characteristics of the Be-Al alloy and then presented details of the mechanism of the effect of added elements on the casting process, mechanical properties and tissue evolution. Finally, the heat treatment technology and the repair of defects via electron beam welding were also demonstrated.…”
