We investigate how macrosegregation formation during directional solidification can be purposefully influenced to form sequences of concentration gradients along rod shaped samples. The effects of sudden changes of the solidification velocity on solute segregation are systematically characterized for conditions with reduced and enhanced melt convection, respectively. We present a solidification routine that is capable of creating alloy samples with specifically designed concentration profiles that are comprised of areas with low solute concentration and peaks of steeply increasing and decreasing solute concentration. The peaks can be adjusted with respect to the concentration interval, width and individual position along the sample. These multiple graded materials are useful for the characterization of (multicomponent) diffusion processes.
