2Fe14B相優(yōu)異的磁性能與高溫穩(wěn)定性，其溫度穩(wěn)定性也得到明顯改善，摻雜后合金的剩磁和矯頑力溫度系數(shù)分別為-0.32%/K和-0.41%/K，與純CeFeB合金相比分別提高了38.5%和40.6%。Y和Zr共摻雜后，由于增加的磁晶各向異性場和晶粒尺寸細(xì)化所產(chǎn)生的聯(lián)合效應(yīng)，合金的矯頑力、剩磁和最大磁能積大幅度提高，分別比純CeFeB合金提高了30.9%、58.1%和204.8%。;Effects of Y and Zr doping on the phase constituent, magnetic properties, and temperature stability for CeFeB alloy were investigated. The results show that CeYFeB alloy consists of the 2:14:1 main phase and a small amount of α-Fe phase. Magnetic properties including coercivity, remanence, and magnetic product energy improve considerably after Y doping. Meanwhile, the temperature stability is enhanced significantly. Due to the excellent intrinsic magnetic properties and higher temperature stability of Y2Fe14B phase, the remanence and coercivity temperature coefficients are -0.32%/K and -0.41%/K, increasing by 38.5% and 40.6%, respectively, compared to those of the pure CeFeB alloy. After the Y and Zr co-doping, the coercivity, remanence, and magnetic product energy improve greatly, increasing by 30.9%, 58.1%, and 204.8%, respectively, compared to those of pure CeFeB alloy, because of the joint effects of enhanced magnet crystalline anisotropic field and refined grain size."/>
