This report presents an innovative approach to solid state alloying using a kirigami inlay to produce functional gradient materials (FGMs). This deformable inlay, which dissolves into the matrix according to the principles of fractal architecture, allows the distribution of alloying elements in the matrix to be controlled during roll-bonding and subsequent heat treatment. The resulting structures exhibit self-similarity due to the geometry of the inlay, which is scalable at different levels. This paves the way to materials with new functional properties
