この発明は、チタン基材合金溶接棒に関し、とくにβ型
チタン合金の溶接に用いた場合に溶接部に生じる延性低
下を防ぐチタン基材合金溶接棒に関するものでおる。Detailed Description of the Invention [Field of Industrial Application] This invention relates to a titanium-based alloy welding rod, and in particular to a titanium-based alloy welding rod that prevents a decrease in ductility that occurs in a welded part when used for welding β-type titanium alloy. This is related to welding rods.
[従来技術]

−3A I、T i −11,5MO−62r −4,
53n、 T i −3A I −8V −6Cr −
4Mo −4Z r等が知られているが、これは成形性
にすぐれ、かつ高強度のチタン合金として注目されてお
り、各方面での利用が期待されている。そうした重要な
分野として溝造物としての利用がおるが、この場合には
溶接に対する適応性が不可欠の要素である。[Prior art] β-type titanium alloy is T i −15V −3Cr −
3Sn-3A I, Ti-13V-11Cr
-3A I, T i -11,5MO-62r -4,
53n, T i -3A I -8V -6Cr -
4Mo-4Zr and the like are known, and this is attracting attention as a titanium alloy with excellent formability and high strength, and is expected to be used in various fields. One such important field is the use as groove structures, and in this case, adaptability to welding is an essential element.
β型チタン合金の溶接には、EB溶接、レーザービーム
溶接、TIG溶接必るいはMIG:8接が採用されてい
る。For welding β-type titanium alloys, EB welding, laser beam welding, TIG welding, or MIG:8 welding is used.
[発明が解決しようとする問題点]
上記の溶接法のうち、EB溶接、レーザービーム溶接は
入熱量が少なく、問題はないが、TIG溶接やMIG溶
接による場合は溶接部に大幅な延性低下を引起すという
問題が生じる。[Problems to be solved by the invention] Among the above welding methods, EB welding and laser beam welding have a small amount of heat input and there is no problem, but TIG welding and MIG welding cause a significant decrease in ductility of the welded part. The problem arises that it causes
このため、このような溶接法による場合には材料を強制
冷却する等の方策を講じる必要があった。Therefore, when such a welding method is used, it is necessary to take measures such as forced cooling of the material.
[問題点を解決するための手段]
この発明者は、このような溶接部における延性の低下を
解決するため鋭意検討してきた。そして、この延性低下
の原因は、β型チタン合金の溶着部が溶融してから同化
、冷却するまでの時間が長く、またその間α相が表われ
ず、β相単独から構成されているために結晶粒径の粗大
化が顕著となる結果、結晶粒界に応力集中を生じ易く、
粒界われを生じ易くなるためであろうと推定した。[Means for Solving the Problems] The inventor has made extensive studies to solve this problem of reduced ductility in welded parts. The reason for this decrease in ductility is that it takes a long time for the welded part of the β-type titanium alloy to melt, assimilate, and cool, and during that time, the α phase does not appear, and it is composed only of the β phase. As a result of the coarsening of the crystal grain size, stress concentration tends to occur at the grain boundaries,
It is assumed that this is because grain boundary cracking is more likely to occur.
そして、イツトリウムやほう素がチタンまたはチタン合
金中で金属間化合物や単体として固溶されて粒界の移動
を妨げ、結晶粒を微細化する作用をもつことに着目し、
このイツトリウムやほう素の作用を利用することによっ
て、前記の延性の低下を改善できるのではないかと考え
、研究を重ねた結果、ついに下記に示す特定の組成をも
つチタン基材合金溶接棒を提供することにより、上記の
問題点を解決するに至った。Then, we focused on the fact that yttrium and boron are dissolved as intermetallic compounds or simple substances in titanium or titanium alloys, and have the effect of hindering the movement of grain boundaries and refining crystal grains.
We thought that the above-mentioned decrease in ductility could be improved by utilizing the effects of yttrium and boron, and as a result of repeated research, we finally developed a titanium-based alloy welding rod with the specific composition shown below. By doing so, we were able to solve the above problems.
すなわち、この発明はβ型チタン合金にイツトリウム0
.002〜0.10重量%および/またはほう素0.0
02〜0.10重量%を含有させたチタン合金よりなる
溶接棒である。In other words, this invention has a β-type titanium alloy containing 0 yttrium.
.. 002-0.10% by weight and/or boron 0.0
This is a welding rod made of a titanium alloy containing 0.02 to 0.10% by weight.
イツトリウム、はう素を0.002〜0.10重量%と
しだのは、0.0021ffi%未満では結晶粒が十分
に微細化しないため、延性低下の防止効果が不十分であ
り、また0、10fflffi%を越えると介在物が多
すぎるため結晶粒径にかかわりなく、材料が脆化するた
め好ましくないからである。The reason for using 0.002 to 0.10% by weight of yttrium and boron is that if it is less than 0.0021ffi%, the crystal grains will not become fine enough, so the effect of preventing ductility reduction will be insufficient; This is because if it exceeds 10fffffi%, there will be too many inclusions and the material will become brittle regardless of the crystal grain size, which is undesirable.
[実施例コ 次に実施例によりこの発明をざらに詳細に説明する。[Example code] Next, the present invention will be explained in more detail with reference to examples.

After the bar material was diced, it was subjected to centerless processing, pickling, and vacuum annealing.
