High performance rare earth-transition metal magnetostrictive materials
Abstract
A high performance rare earth-transition metal magnetostrictive material with increased impurities having the formula (R.sub.x1 R.sub.x2 . . . R.sub.x11).sub.1 (M.sub.y1 M.sub.y2 . . . M.sub.y6).sub.z is provided. Each R is selected from the group of elements consisting of lanthanum, cerium, praseodymium, neodymium, samarium, gadolinium, terbium, dysprosium, holmium, erbium and yttrium, where 0.ltoreq.x1.ltoreq.1, 0.ltoreq.x2.ltoreq.1 . . . 0.ltoreq.x11.ltoreq.1 and where x1+x2+ . . . +x11=1. Each M is selected from the group of elements consisting of iron, manganese, cobalt, nickel, aluminum and silicon, where 0.ltoreq.y1.ltoreq.1, 0.ltoreq.y2.ltoreq.1 . . . 0.ltoreq.y6.ltoreq.1, where y1+y2+ . . . +y6=1 and where 1.8.ltoreq.z.ltoreq.2.1. The material has oxygen impurities, nitrogen impurities and carbon impurities. The oxygen impurities having an atomic percent ranging from 6,011 to 34,000 parts per million. The nitrogen impurities having an atomic percent ranging from 575 to 4,400 parts per million. The carbon impurities having an atomic percent ranging from 939 to 21,000 parts per million. The material exhibits acceptable magnetostrictive strain performance at a reduced cost.

(54) MAGNETOSTRICTIVE BIMETAL
(57)Abstract:
PURPOSE: To obtain magnetostrictive bimetal having superior absolute stroke characteristics by providing a composition consisting of specified percentages of Co, Fe, Mn, Tb and Dy to an alloy having a positive coefft. of magnetostriction and a composition consisting of specified percentages of Co, Fe, Sm and Dy to an alloy having a negative coefft. of magnetostriction.
CONSTITUTION: Magnetostrictive bimetal is composed of two kinds of alloys having positive and negative coeffts. of magnetostriction. The coefft. of magnetostriction is represented by the ratio of the quantity of strain/the strength of an applied magnetic field. A composition consisting of, by weight, 0.01W5% Co, 25W40% Fe, 1W15% Mn, 0.1W25% Tb and the balance essentially Dy is provided to said alloy having a positive coefft. of magnetostriction, and a composition consisting of, by weight, 5W40% Co, 2W35% Fe, 0.01W60% Sm and the balance essentially Dy is provided to said alloy having a negative coefft. of magnetostriction. Magnetostrictive bimetal having superior linearity, superior displacement history characteristics and stable characteristics is obtd. |
