  $\alpha$--cluster states in $^{46}$Cr and $^{54}$Cr are investigated in the
double-folding model. This study complements a recent similar work of Souza and
Miyake \cite{Sou17} which was based on a specially shaped potential. Excitation
energies, reduced widths, intercluster separations, and intra-band transition
strengths are calculated and compared to experimental values for the ground
state bands in $^{46}$Cr and $^{54}$Cr. The $\alpha$-cluster potential is also
applied to elastic scattering at low and intermediate energies. Here, as a
byproduct, a larger radial extent of the neutron density in $^{50}$Ti is found.
