Description
Patented Jan. 14, 1936 PATENT OFFICE PERMANENT MAGNET CONTAINING NICK- EL, ALUMINUM, AND VANADIUM Tokushichi Mishima, Yodobashi-ku, Tokyo, Japan No Drawing.
Original application January 20, 1932, Serial No. 587,822.
Divided and this application August 7, 1935, Serial No. 35,209. In
Japan August 27, 1931 4 Claims.
This invention relates to a strong permanent magnet and forms a divisional from the copendmg application Serial No. 587,822 filed January 20, 1932.
This permanent magnet contains the main ele- 5 ments iron, nickel and aluminum with iron as the basic element, 5 to 40% nickel, 7 to 20% aluminum; and the auxiliary element vanadium from trace to 10% with or without carbon from trace to 1.5%.
10 In original application 587,822 it is described that a so-called "irreversible nickel steel" can be changed into a "reversible steel by the addition of aluminum, thereby obtaining a strong magnetic alloy. According to the invention it has been found that the addition oi a proper amount of other metals as auxiliary elements will further improve the magnetic properties as well as the tenacity and ductility of the permanent magnet and Xacilitate the mechanical working 01 the magnet.
It is well known that the more minute the micro-structure of the magnet steels is, the greater is the increase in the number of molecular magnets arranged irregularly at the boundaries of the crystal grains so that consequently the coercive force and the residual magnetism also increase. This ieature is gained by the addition of certain amounts 01' one or more auxiliary metals to the main elements iron, nickel and alumi- .m num in the proportions herein given.
According to this invention it has been found that the new alloy as mentioned above, can further be improved by the addition of vanadium of below 10%. By this means. the magnetic properties become still further increased and the forging and rolling properties are considerably improved.
Actual examples for this case are given below:
It is also noted in this case that the presence of carbon of below 1.5% and/or a small amount 15 of impurities does not materially affect the magnetic properties of the alloy.
I claim: 1. A permanent magnet comprising 5 to 40% nickel. 7 to 20% aluminum, from trace to 10% o vanadium, and the remainder iron.
2. A permanent magnet comprising 5 to 40% nickel, 'i to 20% aluminum, from trace to 10% vanadium, and the remainder substantially iron.
3. A permanent magnet comprising 5 to 40% 25 nickel, 7 to 20% aluminum, from trace to 10% vanadium, from trace to 1.5% carbon and the remainder iron.
4. A permanent magnet comprising 5 to 40% nickel, 7 to 20% aluminum, from trace to 10% vanadium, from trace to 1.5% carbon and the. remainder substantially iron.
