The effect of scandium on the phase stability of Al sub 3 Nb and Al sub 3 Zr

The effect of scandium on the phase stability of Al sub 3 Nb and Al sub 3 Zr [electronic resource]

A series of Al-25 (Nb,Sc), at. %, and Al-25 (Zr,Sc), at. %, alloy buttons were arc-cast in argon and homogenized for 2 h in vacuum at temperatures ranging from 1473 to 1573K. X-ray powder-diffraction indicated that almost all the Nb in Al-25 Nb (DO₂₂) had to be replaced by Sc in order to obtain the...
