  • Abstract
    A CCIA (controlled cooling and isothermal aging) treatment was adopted to check the reproducibility problem of (Sm,Pr)Co4.6 presented by M. Velicescu (1982) and to improve the magnetic properties of (PrxSm1-x)Co4.6 alloys. It was shown that controlled cooling rate between sintering and isothermal aging temperatures profoundly affects the scattering of magnetic property data. By this CCIA treatment the composite (Sm,Pr)Co4.6 alloy was shown to preserve merits of both SmCo5 and PrCo5 alloys.
