A permanent magnet is obtained by pulverizing, molding and sintering a starting material containing an alloy ingot. The alloy ingot contains not less than 90% by volume of prismatic crystals each having a prismatic crystal grain size of 0.1 to 50 mu m along a short axis thereof and a prismatic cryst ...
An AB5 type age-precipitating rare earth metal-nickel alloy having a composition expressed by (1): R(Ni1-xMx)5+y where R represents one or more of rare-earth elements including Y, M represents one or more selected from a group of Co, Al, Mn, Fe, Cu, Zr, Ti, Mo, W, and B and x and y respectively sati ...
A rare earth metal-nickel hydrogen occlusive alloy ingot contains 90 vol% or more of crystals having a crystal grain size of 1 to 50 mu m as measured along a short axis of the crystal and 1 to 100 mu m as measured along a long axis of the crystal. A method for producing the rare earth metal-nickel h ...
An alloy ingot for permanent magnet consists essentially of rare earth metal and iron and optionally boron. The two-component alloy ingot contains 90 vol% or more of crystals having a crystal grain size along a short axis of 0.1 to 100 mu m and that along a long axis of 0.1 to 100 mu m. The three-co ...
A method comprising the steps of preparing crushed material by crushing nickel-hydrogen secondary cells; separating alkalis, organic substances, and iron from the crushed substance in order to obtain a separated material from which at least alkalis, organic substances, and iron are separated; burnin ...
