Abstract Scope |
Finemet (Fe73.5Cu1Nb3Si13.5B9) is an iron-based softmagnetic alloy that has excellent magnetic properties such as high permeability and saturation magnetization as well as low coercivity. The influence of mechanical alloying (MA) parameters and Spark Plasma Sintering (SPS) process on microstructure, mechanical properties and magnetic properties of Finemet alloys is investigated in this research work. Finemet powder was milled for 30, 60, 90, and 120h with ball to powder ratio (BPR) of 10:1 and 15:1. The milled powder was consolidated using the SPS process. Furthermore, coercivity and saturation magnetization as well as microhardness of the samples were measure in order to investigate the role of MA parameters on magnetic and mechanical properties of the alloys. Moreover, microstructure was studied by Scanning Electron Microscop (SEM) analysis and X-ray Diffraction (XRD) was conducted on milled powders as well as sintered alloys in order to investigate the phases present before and after the sintering occurs. |
