AI Technical Summary
In existing aluminum alloy powder metallurgy methods, compressor components prepared by aluminum alloys exhibit insufficient bonding between aluminum alloy particles under high temperature and high speed rotation conditions, leading to reduced elongation and fatigue properties.
Aluminum alloy powder with specific chemical composition is compacted and hot-extruded using powder metallurgy to form Al-Fe intermetallic compounds, which improves the bonding strength between particles. Mg is used to break the oxide film, thereby enhancing the elongation and fatigue properties of the aluminum alloy material.
Excellent elongation and fatigue characteristics of compressor components were achieved under high temperature and high speed rotation conditions, improving the mechanical properties and durability of the components.
