The use of high‐throughput techniques allows for rapid property‐driven materials development. Attractive material profiles are systematically screened and processed on the example of the ternary Fe–C–Cr system into yet unexplored regions. The effect of various combinations of Cr additions (2, 4, 6, 8, 10 wt%) on the mechanical properties and microstructures of Fe–0.2C (wt%) and Fe–0.8C (wt%)‐based steels are studied depending on their hardening (850–1150 °C; 20 min) and tempering conditions (100–600 °C; 1 h), producing 120 different material states. Wide ranges of potentially interesting material profiles are obtained with strengths up to 1.8 GPa ultimate tensile strength (UTS) or hardness of 700 HV5. Individual trends for materials’ mechanical performance are identified, but straightforward interpretation of trends holds complex multi‐dimensional analytical challenges of this high‐throughput bulk metallurgical screening. Methods addressing these problems are outlined and the possibilities of assistive computational data processing and analysis are discussed.
