Abstract Scope |
Conventional methods of alloy discovery are very time-consuming and expensive, especially for challenging material systems such as superalloys. Material libraries that allow the measurement of bulk material properties can significantly accelerate alloy design efforts. Surface remelting of specimens of varying compositions in contact with each other can be used to create a composition gradient through intermixing and therefore produces such bulk material libraries. Herein, the CrCoNi medium entropy system and a CoNi-based superalloy system with a varying ć’-content and a Co/Ni-ratio transition were analysed using bulk material libraries produced by the laser surface-remelting technique. The mm-scaled intermixed volume in the material libraries facilitate characterisation methods such as profilometry-based indentation plastometry, X-ray diffraction and electron-probe microanalysis. Microstructure and mechanical properties were determined and related to the local composition. In summary, it is shown that unknown structural material systems can be effectively assessed using material libraries created using the laser surface-remelting technique. |
