【 摘 要 】
A micro-addition (0.025 at.%) of slow-diffusing W to an Al-0.26Mn-0.11Mo-0.11Si-0.08Zr-0.02Sc-0.01Er (at.%) alloy accelerates L1(2)-Al-3(Zr,Sc) precipitation but retards alpha-Al(Mn,Mo)Si precipitation. The W micro-addition increases the peak-microhardness of the alloy during isothermal aging but does not improve the coarsening resistance and creep resistance.
