The isothermal section phase diagram of the Sm-Fe-Ni ternary system at 800 degrees C

摘要

Isothermal section at 800 degrees C of the ternary Sm-Fe-Ni system was established in the whole concentration range, by means of powder X-ray diffraction and scanning electron microscopyenergy dispersive X-ray spectroscopy (SEM/EDS). All measured compositions and unit-cell refinements were performed at room temperature from quenched samples annealed at 800 degrees C for one week. Ten binary compounds and a(Fe1-x Ni-x) (Im-3m-W type structure) have been confirmed.
