摘要：
The Nd9.5Fe84B6.5 ribbons were prepared by melt-spinning. The effects of chamber pressure and wheel speed on the magnetic property and microstructure of Nd9.5Fe84B6.5 alloy were investigated. A complementary relationship between the chamber pressure and the wheel speed in rapid solidification of melt-spinning was proposed. The values of thickness and magnetic property in the ribbon sample prepared at a chamber pressure of 0.03 MPa and a wheel speed of 19 m/s are similar to those prepared at a chamber pressure of 0.05 MPa and a wheel speed of 15 m/s. XRD and TEM results show that the ribbons prepared under the two conditions have the same phase composition and similar microstructure. The melt-spun Nd9.5Fe84B6.5 ribbons with similar magnetic properties and microstructure can be obtained by controlling the chamber pressure and wheel speed in rapid solidification.
