Study of magnetic properties of sintered alloy Fe-Cr ODS using VSM

Abstract

In this experimental work Vibration Sample Magnetometer (VSM) was used to study the magnetization property of ultrasonic assisted sinter material ODS Fe-Cr containing dispersoid particles Y2O3. The results of magnetization diagram analysis showed an anisotropy with saturation values 150 and 200 emu/gr for the angles 270 and 360°, respectively. Although higher saturation level, the alloy exhibits exceptionally small hysteresis loop with very low remanence and coercivity. As powder Fe-Cr mixture before sintering has maximum saturation 200 emu/gr. Properties combination of anisotropy, the absent of hysteresis loop and high saturation value has been opened new research opportunity on application of Fe-Cr based ODS material in field of sensors and magnetic assisted electro mechanic parts such as transformers and motors.
