There is a sealing alloy called Fe). In the United States, Japan, West Germany, etc., we are conducting research to improve the performance of this alloy.

部品を作ることができません。Since the crystal grains of the above conventional sealing alloy are coarsened after high temperature annealing, the stress corrosion resistance is poor. In this alloy, wrinkled defects are likely to occur on the surface of drawn parts,
Alternatively, when brazing with silver, the phenomenon of permeation easily occurs at the grain boundaries of the silver braze, and the hydrogen embrittlement resistance and stress corrosion resistance deteriorate. However, in practice, the annealing temperature must be lowered in order to prevent the coarsening of the crystal grains at high temperatures. However, if so, the life of electronic components will be shortened, and as a result, it will not be possible to make components such as electron tubes that have long life and high output.

It has been proposed that 0.005 to 1.5% (wt%) rare earth metal is added to make the crystal grains finer, thereby suppressing the grain boundary permeation phenomenon of silver solder (Japanese Patent Publication No. 46-57974). Zr metal added to pure iron and carbon steel (Japanese Patent Publication No.
18408) or a Ni-Cr-Fe alloy with Ti metal (Japanese Patent Publication No. 50-57916) to suppress inter-grain corrosion and cracks. However, the effects of these are not so remarkable, and it is recognized that they are completely different from the alloy of the present invention.

は、耐応力腐食性を向上するためである。In other words, the present invention is based on the known Fe-Ni-Co system or Fe-Ni.
This is a method in which 0.02 to 0.8% of Zr is added to a —Co—Cu based sealing alloy, the alloy is heated to 1100 to 1200 ° C., hot rolled, and then water quenched at 950 ° C. or higher. The reason for adding Ni, Co, and Cu and the reason for limiting the range of addition are the same as those for known sealing alloys, and the description thereof is omitted here. The reason for adding Zr is to improve the stress corrosion resistance.

添加する通常の方法によって得られる。That is, the added Zr can react with N 2 in the alloy to refine the crystal grains and form uniformly dispersed ZrN. Z
The size of rN particles is from several hundred Å to 1 μm. When annealing is performed, ZrN first precipitates at the grain boundaries where strain is occurring, so movement of the grain boundaries can be prevented during high temperature annealing. It has the effect of suppressing the coarsening of crystal grains and improving the stress corrosion resistance of the alloy. The reason why the addition range of Zr is limited is that the effect is not exhibited when the content is less than 0.02%, and the property of the alloy deteriorates when the content exceeds 0.8%. This alloy can maintain the expansion characteristics and improve the sealing property with hard glass or ceramics. The alloy of the present invention can be obtained by a usual method of adding various additive elements to molten iron in the form of a simple substance or a mother alloy.
Fe−Ni−Co系或はFe−Ni−Co−Cu系合金にZrを0.02〜0.

The reason for adding 8% (wt%) and limiting the addition amount as described above is as follows. Since the grain refining effect of Zr is influenced by the melting method and the contents of N 2 and O 2 in the alloy, Z
The content of r has the best effect when observing the equivalence ratio of ZrN. For example, the best Zr content when melting in vacuum is 0.05
~ 0.06% (wt%), when N 2 0.002% and O 2 0.001% are contained in the alloy when vacuum tube sealing is performed by argon welding, the Zr content is less than 0.16% (wt%) Is good. 11
It is heated at 00 ℃ -1200 ℃ and hot-rolled.
