Abstract：

Influence　of　annealing　on　electrical　conductivity　and　hardness　of　Al-Er-Cu　alloys　was　investigated　by　means　of　electrical　conductivity　test,　hardness　test　and　transmission　electron　microscopy.　The　results　indicate　that　high　hardness　and　electrical　conductivity　of　the　Al-Er-Cu　alloys　are　obtained　after　isochronal　annealing　to　between　200　and　300℃　or　isothermal　annealing　at　200℃　for　24　to　48　h.　Al3Er　phase　precipitating　during　annealing　can　enhance　thermal　stability　of　the　cold　rolling　microstructure　and　retard　the　declining　of　hardness　of　the　Al-Er-Cu　alloys.　Al2Cu　precipitation　leads　to　the　increase　of　the　electrical　conductivity　of　the　Al-Er-Cu　alloys.　©　2017,　Editorial　Office　of　Transactions　of　Materials　and　Heat　Treatment.　All　right　reserved.
