  • Alloy thin ribbon for rare earth magnet, production method of the same, and alloy for rare earth magnet
    Patent number: 7279053
    Abstract: The present invention provides a rare earth magnet superior in magnetic properties and thermal stability. In an aspect of the present invention, a production method of an alloy thin ribbon for a rare earth magnet includes a step to obtain a quenched thin ribbon by feeding a molten alloy containing praseodymium (Pr), iron (Fe), cobalt (Co), titanium (Ti), boron (B), and silicon (Si) on a rotating roll and a step to apply heat treatment to the quenched thin ribbon at a heating rate within a range of 100° to 150° C./min to crystallize the quenched thin ribbon.
