To obtain the Pr-Fe-B ternary system magnets with higher (BH)max, the effect of composition ratio and various heat-treatment temperatures on the magnetic properties of Pr-Fe-B system rare-earth magnets were investigated.<br/>
The magnets with various composition of Pr and Fe were heat-treated at 990 ℃, 625 ℃, 585 ℃, 550 ℃ after sintering.<br/>
Curie temperature is 310 ℃ and quantitative analysis by SEM, EDX shows that the Pr₂Fe₁₄B, Pr-rich phase consist of Pr~14 at.% and Fe~86 at.%, Pr~58 at.% and Fe~42 at.%, respectively, The coercivity is decreased after heat-treating at 990 ℃ and increased from 5.6 to 6.3 kOe at 625 ℃. The maximum energy product is decreased from 43.4 to 30.3 MGOe after the heat-treating at 990 ℃ but increased from 42.7 to 45.0 MGOe, about 5 %, by heat-treating at 625℃.
