摘要: Determining the dominant creep mechanism is key feature for design and development of Al-Fe alloys. The tensile behavior Al5Fe4Cu2ZnMnMg alloy (AF1) Al5Fe4Cu2CrZnZrMnMg (AF15) by prepared semisolid forming has been investigated. results reveal that steady-state rates AF1 AF15 alloys are increased with increasing temperature applied stress. property slightly higher than alloy. There threshold stress during creep. true exponent close to 5. controlled lattice diffusion aluminum. resistance significantly improved adding a small amount Cr Zr elements reasons life discussed.
