Conclusion

The increase in strength and plasticity of an aluminum alloy with additives of REM, zirconium, and hafnium in comparison to alloys containing iron is associated with 1) a more refined grain structure; 2) a full or partial supression of recrystallization; 3) the direct strengthening action of the dispersoid particles.

Zirconium and hafnium accelerate the decay of the solid solution of zinc, magnesium, and copper in aluminum during aging. This causes a loss of strength during the precipitation aging stage with these alloys in comparison with alloys containing REM.

REM do not affect the size and density of the precipitated strengthening ν phase (MgZn2) in Al−Zn−Mg−Cu alloys.
