Abstract Scope |
Recent processing results have shown that dilute P additions may be a viable route to promote formation of chemically ordered phases in the Fe-Ni system. The Fe-Ni L10 phase is a potential replacement for rare-earth permanent magnets but has only been found in bulk form within meteoric material due to incredibly slow kinetics in its equilibrium range. The magnetic behavior of the Fe-Ni system at compositions ranging from 37.5 - 52.5 at% Ni and 0, 0.25% and 0.5% P alloying additions will be reported for the first time in the form of vibrating sample magnetometry hysteresis loops, comparing both the homogenized and quenched solid solution, as cast samples, and samples aged at moderate temperatures to induce P diffusion to precipitates, which is expected to promote chemical ordering and enhance magnetocrystalline anisotropy. |
