In order to reduce the segregation of alloy components, overcome the defects of shrinkage pores, and improve the comprehensive strength level of beryllium aluminum alloys, powder metallurgy is usually used in engineering to prepare beryllium aluminum alloys. However, while meeting the strength and functional requirements, the phase interface faces the alloy material. Its role cannot be ignored.
The composite material forms an interface or interface layer at the combination of two components of different components. The mechanical properties of the interface have a great influence on the performance and failure mechanism of the composite material. In order to meet the needs of composite materials in engineering, people usually The interface is designed and optimized, so the research of the interface has been the focus of academic circles.
Since the covalent bonds of the alloy system are reduced when cobalt and germanium are added, the cobalt and germanium are added to improve the intrinsic brittleness of the beryllium aluminum alloy. However, the number of overlapping populations between the beryllium and aluminum atoms across the interface around cobalt and germanium has increased compared to before addition, which makes the beryllium and aluminum atoms at the interface strengthen the bonding effect and improves the beryllium-aluminum alloy interface. The bonding strength at the position is conducive to interfacial bonding.
