Study on Crystallization Temperature and Time of Amorphous Sm-Fe Alloy AITranslate
Abstract AITranslate
The microstructure and phase composition of Sm-Fe alloy with 24% Sm in different crystallization stages were determined by means of XRD,SEM and DSC.The effects of temperature and time on the crystallization of amorphous Sm-Fe alloy were studied.The results show that even if the rapid quenching speed reaches 35 m/s and the cooling rate reaches 1.03×10^6 K/s,only 10%~20% amorphous content can be obtained in rapidly quenched ribbons of Sm-Fe alloy.After the rapidly quenched ribbons are ball-milled for 2.5 h,the main phase Sm2Fe17 has become complete amorphous,and only a small amount of α-Fe phase exists in the alloy.The optimal crystallization temperature and time of the amorphous powder from 2.5 h ball milling of Sm-Fe alloy ribbons are 700 ℃ and 20 min,respectively.
