Cellular microstructure modification and high temperature performance enhancement for Sm2Co17-based magnets with different Zr contents
文献摘要：
Influence of Zr contents on high-temperature magnetic performance of Sm(CobalFe0.09Cu0.09Zrx)7.2(x = 0.025,0.03,0.035,0.04)magnets were investigated.As x increases from 0.025 to 0.04,the tem-perature coefficient of intrinsic coercivity(Hcj)is optimized from-0.1673％K-1 to-0.1382％K-1 and the Hcj at 773 K gradually increases from 556.32 kA m-1 to 667 kA m-1.The microstructure and microchem-istry of different Zr-content magnets were revealed by a transmission electron microscope equipped with EDS.The increasing Zr content induces that the average size of cells decreases from～76 nm to～56 nm and the weight fraction of 1:5H cell boundary phase increases from～25％to～37％as well,resulting decreasing of the average Cu content at cell boundaries from 13.59 at％to～8.52 at％.It is found that the Cu-lean characteristic at cell boundary phase is the reason that gives rise to higher magnetic properties at elevated temperatures for x = 0.04 magnet.
