A systematic analysis of the $\alpha$ + core structure is performed in theground state bands of even-even nuclei of the $22 \leq Z \leq 42$ region interms of the Local Potential Model. The $\alpha$ + core interaction isdescribed by the nuclear potential of (1 + Gaussian)$\times$(W.S. + W.S.$^3$)shape with 2 free parameters. Properties such as energy levels, reduced$\alpha$-widths, $B(E2)$ transition rates and rms charge radii are calculatedand compared with experimental data. A good agreement with the experimentaldata is obtained in general, even for the nuclei without the $\alpha$ + {doublyclosed shell core} configuration. The analysis of the selected nuclei in the$22 \leq Z \leq 42$ region indicates that $^{44}$Ti and $^{94}$Mo have agreater $\alpha$-clustering degree in comparison with their respectiveneighboring nuclei of this set. In addition, the model points to the existenceof nuclei without the $\alpha$ + {doubly closed shell core} configuration witha significant $\alpha$-clustering degree compared to $^{44}$Ti, $^{60}$Zn, and$^{94}$Mo. The study shows that the $\alpha$ + core approach is satisfactorilyapplicable to nuclei other than those with $\alpha$-clustering abovedouble-shell closures.
