    摘要: Disclosed is a thin alloy ribbon prepared by the strip casting method as an intermediate for the preparation of a sintered rare earth-based permanent magnet or in particular, a neodymium/iron/boron-type permanent magnet. The thin alloy ribbon is characterized by a specific volume fraction of the four-phase coexisting region consisting of the &agr;-iron phase, R-rich phase, RxT4B4 phase and R2T14B phase each having an average grain diameter in a specified range and a specific volume fraction of the chill crystalline phase. When these requirements are satisfied, the sintered rare earth-based permanent magnet prepared from the thin alloy ribbons can be imparted with improved magnetic properties and high sintering density even without increasing the sintering temperature.

    摘要: An FE--Ni--Cr-base superalloy consists essentially of, by weight, up to 0.15% C, up to 1.0% Si, up to 3.0% Mn, 30 to 49% Ni, 10 to 18% Cr, 1.6 to 3.0% Al, one or more elements selected from Groups IVa and Va whose amount or total amount is 1.5 to 8.0%, the balance being Fe, optionally, minor amounts of other intentionally added elements, and unavoidable impurities. The optional other elements which can be intentionally added to or omitted from the alloy include Mo, W, Co, B, Mg, Ca, Re, Y and REM. The superalloy is suitable for forming engine valves, knitted mesh supporters for exhaust gas catalyzers and the like, and has excellent high-temperature strength and normal-temperature ductility after long-time heating, as well as sufficient oxidation resistance properties for these uses.
