چکیده

در این تحقیق، خواص مغناطیسی آلیاژهایFe-P بررسی شده است. بررسیها نشان دادند که پس از انجام یک عملیّات حرارتی دو مرحله ای، بزرگی نیروی وادارندگی در نمونهها کاهش مییابد. افزون بر این، با افزایش مقدار فسفر در آلیاژ، مقاومت ویژه افزایش یافت. بررسی های میکروسکُپی نشان دادند که تمامی نمونه ها عاری از رسوبهای Fe3P هستند و افزایش فسفر منجر به افزایش اندازهی متوسط دانه و در نتیجه، کاهش اتلاف هیسترزیس در نمونهها می شود. بهاین ترتیب، مشخص شد که آلیاژ at. %P1 / 1Fe- دارای کمترین مقدار اتلاف هیسترزیس، اتلاف جریانهای گردابی و همچنین، بیشترین مقدار القای اشباع مغناطیسی است.

چکیده [English]

In the present work, the magnetic properties of Fe-P alloys were investigated. The investigations showed that the magnitude of coercivity decreased by conducting two annealing treatments on samples. Samples having the highest amount of Phosphorous exhibited the lowest resistivity. Microstructural studies revealed that the prepared samples were free from Fe3P precipitate and the average grain size increased with an increase in the Phosphorous content giving rise to the decrease of hysteresis losses. Furthermore, amongst the whole prepared samples, Fe-1.1at.%P alloy showed the lowest hysteresis loss and eddy current loss as well as the highest magnetic induction.
