【発明の詳細な説明】 （産業上の利用分野） 本発明は圧延接合法によるチタンクラッド鋼板の製造方
法に関するものである。TECHNICAL FIELD The present invention relates to a method for producing a titanium clad steel sheet by a rolling joining method.
（従来技術） 従来より、チタンクラッド鋼板の製造法としては、爆着
法、圧延接合法及び爆着圧延法が広く知られている。(Prior Art) Conventionally, as a method for producing a titanium clad steel sheet, an explosion-bonding method, a roll-bonding method, and an explosion-bonding rolling method are widely known.
しかし、爆着法は、合せ材を爆薬の爆発エネルギーによ
り母材と接合させるため、合せ材と母材の接合界面に炭
化物や金属間化合物などが生成せず、比較的良好な接合
強度が得られるが、種々の要因から薄物や長尺、広幅材
は製造が不可能であり、また大量生産が難しく、コスト
アップにつながるといった問題があった。However, in the explosive deposition method, the joining material is joined to the base material by the explosive energy of the explosive, so carbides and intermetallic compounds are not generated at the joining interface between the joining material and the base material, and relatively good joining strength is obtained. However, due to various factors, it is impossible to manufacture thin materials, long materials, and wide materials, and mass production is difficult, which causes a problem of cost increase.
また、圧延接合法では、熱間圧延時及びその後の冷却
中、合せ材と母材の接合界面に、Ti、Fe、Ｃ等の相互拡

成し、接合性を劣化させるという問題がある。そこで、
このような脆化層を抑制する目的で、合せ材と母材の接
合予定面に種々のインサート材を介在させる方法が試み
られているが、脆化層の生成を防止し得る適切なインサ
ート材が見い出されているとは云い難い。In the rolling joining method, intermetallic compounds, carbides, and ω transformation structure of Ti are generated at the joining interface between the laminated material and the base material by mutual diffusion during hot rolling and during cooling thereafter. However, there is a problem that the bondability is deteriorated. Therefore,
For the purpose of suppressing such an embrittlement layer, a method of interposing various insert materials on the joining scheduled surfaces of the mating material and the base material has been attempted, but an appropriate insert material capable of preventing the formation of the embrittlement layer It is hard to say that has been found.
更に、爆着圧延法は、爆着と圧延の両工程を要するため
に製造コストが高くなるという問題のほか、加熱中、Ti
中へのFe、Ｃ等の拡散に起因して接合力が低下すること
が大きい問題として残されている。Furthermore, the bombing and rolling method has the problem that the manufacturing cost is high because both the bombing and rolling steps are required,
It remains a big problem that the bonding force is reduced due to diffusion of Fe, C, etc. into the inside.
（発明が解決しようとする課題） 上記各種接合法のうち、圧延接合法における問題点を更
に詳細に説明すると、以下のとおりである。(Problems to be Solved by the Invention) Of the various joining methods described above, the problems in the rolling joining method will be described in more detail below.
圧延接合法では、前述の如く合せ材（チタン）と母材
（炭素鋼）の接合界面に生成する脆化層を防止する方法
として、フェライト系ステンレス鋼、マルテンサイト系
ステンレス鋼、Nb、Ta、Mo、Ｖ等の薄板又は箔をインサ
ート材として介在させる方法が提案されている。この方
法によれば、合せ材と母材の間の相互拡散によるTiC等
の炭化物や金属間化合物の生成を抑えることは可能であ
るが、Tiのω変態組織の生成を防止するには十分でな
い。In the rolling joining method, as described above, as a method for preventing the embrittlement layer generated at the joining interface between the laminated material (titanium) and the base material (carbon steel), ferritic stainless steel, martensitic stainless steel, Nb, Ta, A method of interposing a thin plate or foil such as Mo or V as an insert material has been proposed. According to this method, it is possible to suppress the formation of carbides such as TiC and intermetallic compounds due to the mutual diffusion between the laminated material and the base material, but it is not sufficient to prevent the formation of the ω transformation structure of Ti. .
すなわち、これらインサート材に含有されるCr、Nb、T
a、Mo、Ｖ等のβ安定化元素が合せ材中へ拡散移行する
と、チタンのα−β変態温度を下降させてβ相領域を拡
げ、合せ材の接合界面近傍の組織がα相に富むことにな
る。その結果、圧延後の連続冷却過程において、β相が
α相に変態する際に中間遷移相であるω相が生成した
り、室温まで持ち来たされた残留βが施工時の加熱によ
り分解する過程でω相が生成し、接合界面は非常に硬く
且つ脆くなり、接合性は極めて悪くなるという問題があ
る。That is, Cr, Nb, T contained in these insert materials
When β-stabilizing elements such as a, Mo, and V diffuse and migrate into the composite, the α-β transformation temperature of titanium is lowered to expand the β-phase region, and the structure near the bonding interface of the composite is rich in α-phase. It will be. As a result, in the continuous cooling process after rolling, the ω phase, which is an intermediate transition phase, is generated when the β phase is transformed into the α phase, and the residual β brought to room temperature is decomposed by heating during construction. There is a problem that the ω phase is generated in the process, the bonding interface becomes very hard and brittle, and the bondability becomes extremely poor.
本発明の目的は、従来の圧延接合法によるチタンクラッ
ド鋼板の製造おける上記欠点を解消し、優れた接合性を

ある。An object of the present invention is to provide a method for manufacturing a titanium clad steel sheet having excellent bondability by solving the above-mentioned drawbacks in the conventional manufacturing of a titanium clad steel sheet by a rolling bonding method.
（課題を解決するための手段） 上記目的を達成するため、本発明者らは、従来の圧延接
合法の欠点を解消でき、接合性を向上し得る新たな方策
を見い出すべく鋭意研究を重ねた結果、インサート材の
態様が接合性に大きく影響を及ぼす要因であることに鑑
みて、少なくとも２種類のインサート材を使用する態様
で、しかもそれぞれが異なる特定の材質のインサート材
とすることにより、可能であることを見い出し、ここに
本発明をなしたものである。(Means for Solving the Problem) In order to achieve the above object, the present inventors have conducted earnest research to find a new method capable of solving the drawbacks of the conventional roll bonding method and improving the bondability. As a result, in view of the fact that the form of the insert material greatly affects the bondability, it is possible to use at least two types of insert materials, and by using insert materials of different specific materials. That is, the present invention is made here.
すなわち、本発明に係る接合性の優れたチタンクラッド
鋼板の製造方法は、要するに、チタン又はチタン合金を
合せ材とし、炭素鋼を母材としたチタンクラッド鋼板を
圧延接合法によって製造するに当り、合せ材と母材の接
合予定面に、母材側に第１インサート材としてフェライ

低炭素鋼、Nb、Ta、Fe、Mo、Cr、Ｖ及びNiのうちの１種
又は２種以上を介在させ、更に合せ材側に第２インサー
ト材としてα型チタン合金又はα＋β型チタン合金を介
在させることを特徴とするものである。That is, the method for producing a titanium clad steel sheet having excellent bondability according to the present invention is, in short, a titanium or titanium alloy as a composite material, in producing a titanium clad steel sheet having a carbon steel as a base material by a rolling joining method, Ferrite stainless steel, martensitic stainless steel, ultra-low carbon steel, Nb, Ta, Fe, Mo, Cr, V and Ni are used as the first insert material on the base material side of the joining surface of the laminated material and the base material. One or two or more of them are interposed, and an α-type titanium alloy or an α + β-type titanium alloy is further interposed as a second insert material on the mating material side.
（作用） 以下に本発明を更に詳細に説明する。なお、便宜上「チ
タン又はチタン合金」を総称して「チタン」と称する。(Operation) The present invention will be described in more detail below. For convenience, "titanium or titanium alloy" is generically referred to as "titanium".
本発明は、圧延接合に際し、第１図に示す如く母材１側
に第１インサート材31を、合せ材２側に第２インサート
材32をそれぞれ介在させることが特徴の１つである。One of the features of the present invention is that the first insert material 3 1 is interposed on the base material 1 side and the second insert material 3 2 is interposed on the mating material 2 side during roll bonding as shown in FIG. .
この第１インサート材は、母材（炭素鋼）中のFe、Ｃが
合せ材側へ拡散移行するのを防止し、TiC等の炭化物、T
i-Fe系金属間化合物が生成するのを抑制する効果を有す
るものである。This first insert material prevents Fe and C in the base material (carbon steel) from diffusing and transferring to the side of the composite material, and carbides such as TiC and T
It has the effect of suppressing the formation of i-Fe-based intermetallic compounds.
このため、第１インサート材としては、フェライト系ス
テンレス鋼、マルテンサイト系ステンレス鋼、極低炭素
鋼、Nb、Ta、Fe、Mo、Cr、Ｖ及びNiのうちの１種又は２
種以上を薄板状、箔状当で使用する。Therefore, as the first insert material, one or two of ferritic stainless steel, martensitic stainless steel, ultra low carbon steel, Nb, Ta, Fe, Mo, Cr, V and Ni is used.
The seeds or more are used in the form of thin plate or foil.
例えば、１種類だけ使用する場合は、フェライト系ステ

めには、Ｃの拡散阻止効果のより大きいNi、Fe又は極低
炭素鋼を用いればよいが、これらの薄板又は箔を単独で
使用すると、チタンとの接合界面に金属間化合物が生成

更にその上に重ね合わせて使用することにより、脆化層
の生成防止の効果を増大させることができる。For example, when only one type is used, ferritic stainless steel, martensitic stainless steel, Nb, Ta, M
By inserting any one of o, Cr, and V on the base metal side, an intermetallic compound is not generated and C diffusion can be prevented. In order to further increase the diffusion inhibition effect of C, Ni, Fe or ultra-low carbon steel having a larger diffusion inhibition effect of C may be used. However, when these thin plates or foils are used alone, they are Since an intermetallic compound is easily generated at the joint interface, embrittlement occurs by using one or more of ferritic stainless steel, martensitic stainless steel, Mo, Cr and V on top of it. The effect of preventing the formation of layers can be increased.
次に、第２インサート材は、合せ材（チタン又はチタン
合金）側に、すなわち、前述の第１インサート材と合せ
材の間に介在させるものである。Next, the second insert material is interposed on the side of the composite material (titanium or titanium alloy), that is, between the first insert material and the composite material.
第１インサート材中のCr、Fe、Mo、Ｖ、Niの元素はチタ

は、これらの中に含有されるα安定化元素が、チタンの
α−β変態温度を上昇させることによりα相領域を拡大
させ、β相の生成を抑える効果である。もう１つの効果
は、α安定化元素により、仮りに室温までβ相が残留し
たとしても、再加熱時のβ→ω変態を抑制することがで
きる効果である。Since the elements of Cr, Fe, Mo, V, and Ni in the first insert material are β-stabilizing elements with respect to titanium, if these elements diffuse into titanium, the α-β transformation temperature of titanium is lowered. The β-phase region will be expanded. Therefore, by using the α-type titanium alloy or the α + β-type titanium alloy together as the second insert material, two effects can be obtained. One of them is that the α-stabilizing element contained therein increases the α-β transformation temperature of titanium, thereby expanding the α-phase region and suppressing the production of β-phase. Another effect is that the α-stabilizing element can suppress the β → ω transformation during reheating even if the β phase remains at room temperature.
なお、母材としての炭素鋼の材質は制限されず、同様
に、合せ材としてのチタンは勿論のこと、チタン合金の
材質も制限されないことは云うまでもない。また本圧延
接合法における条件も特に制約はない。It is needless to say that the material of the carbon steel as the base material is not limited, and similarly, the material of the titanium alloy as well as the material of the titanium alloy is not limited. Further, there are no particular restrictions on the conditions in the present rolling joining method.
