Abbreviated Series Title |
The microhardness of Al-0.06 Sc-0.02 RE (at.%, with RE = Dy, Er, Gd, Sm, Y, or Yb) alloys is measured as a function of aging time at 300C. As compared to Al-0.08 Sc, the ternary alloys exhibit: (i) the same incubation time, except for Al-0.06 Sc-0.02 Yb which hardens much faster; (ii) the same or reduced peak microhardnesses (which are higher than for Al-0.06 Sc) and (iii) the same overaging behavior. All RE segregate to the core of Al3(Sc1-xREx) precipitates. |
