Mechanical Alloying of Fenicomnti: Formation, Microstructural and Magnetic Properties

The mechanical alloying process that was used to successfully manufacture the high entropy alloy FeNiCoMnTi is described in detail in the following sections of this document (HEA). X-ray diffraction analysis, transmission electron microscopy, and scanning electron microscopy with energy dispersive spectroscopy were the techniques that were used to detect the phase of the formed alloys and investigate the microstructure of the generated alloys. Using a vibrating sample magnetometer, we were able to characterize the magnetic properties of the HEA samples. Based on the magnetic data, the alloys that were created may be classified as semi-hard magnetic material, with MS values of 54 emu/g and HC values of 102 Oe, respectively. Using the Johnson-Mehl-Avrami model as a foundation, kinetic studies determined that the process of forming FeNiCoMnTi HEA involves nucleation at a constant rate followed by a growth that is regulated by diffusion. This was shown to be the case.
