Conclusions
The addition of Ti, Zr, Nb, W, Mo, or V to alloy AL9V reduces the decomposition rate of the solid solution during aging. One of the possible reasons for this is the distortion of the lattice of the matrix due to the difference between the atomic radius of the alloying element and aluminum.
