Magnetic properties of ND Rich Melt-Spun ND-FE-B alloy

Abstract

As a part of these experimental investigations of melt-spun Nd-Fe-B alloy with Nd rich content in relation to Nd2Fe14B prepared by rapid quenching process for optimally selected cooling rate and heat treatment, the influence of the chosen chemical composition on magnetic properties was observed. The results of X-ray diffraction, Mössbauer spectroscopy phase analysis and magnetic measurement of investigated melt-spun Nd14.5Fe78.5B7 alloy are presented to bring some new information concerning the relation between their structure and magnetic properties.

Istraživana melt-spun Nd14,5Fe78,5B7 legura sa sadržajem Nd iznad stehiometrijskog sastava Nd2Fe14B, dobijena je metodom brzog hlađenja, optimalno odabranom brzinom hlađenja. Razmotren je uticaj hemijskog sastava i primenjenog režima termičke obrade na magnetna svojstva. Eksperimentalni rezultati XRD analize i Mössbauer spektroskopske fazne analize korelisani su sa izmerenim magnetnim osobinama u cilju dobijanja novih saznanja za tumačenje relacije mikrostruktura - magnetna svojstva.
