Study on Phase Transformation and Microstructure of Pr-Fe-B Alloy AITranslate
Abstract AITranslate
The phase composition,phase transformation and microstructure of Pr-Fe-B alloy prepared by arc melting were characterized by X-ray diffractometer,differential scanning calorimeter and electron probe microanalyzer.The results show that the main phases in the as-cast microstructure of Pr5Fe75B20 alloy are Pr2Fe14B,Pr1.1Fe4B4,Fe2B and fcc-Fe,while those of Pr18Fe75B7 alloy are Pr2Fe14B,Pr1.1Fe4B4,α-Fe,dhcp-Pr and Pr2Fe17.With the increase of boron content in the alloy,the content of dhcp-Pr phase significantly decreases.The non-equilibrium solidification of Pr-Fe-B ternary alloy was simulated using calculation of phase diagram with Scheil module of Thermo-Calc software.The calculated results are in good agreement with the experimental results,which provides basic data for the composition and microstructure design of Nd-Pr-Fe-B permanent magnetic alloy.
