摘要
The grain size of the Al-Mg-Mn-Zr-Sc-Y alloy was 45 mu m. Al3Mg2, Al3Y and ternary AlMgY phases were formed in the as cast condition. High hardening effect in 64HV was obtained after rolling. The optimal combination of strength and plasticity was achieved after annealing at 150 degrees C: YS = 365 MPa, UTS = 423 MPa and El. = 8.3%. (C) 2018 Elsevier B.V. All rights reserved.
