Definitions
- the present invention relates to a method for producing an aluminum alloy clad material used for structural members and parts of automobiles, ships, aircrafts and the like.
- a method for producing an aluminum alloy clad material has been performed by hot rolling as shown below, for example.
- a core material and a skin material are prepared according to the target cladding rate.
- the core material has a predetermined thickness by chamfering the ingot.
- the skin material is rolled to a predetermined plate thickness through face milling and hot rolling of the ingot, and cut according to the length of the core material alloy.
- the core material and the skin material are combined, heated before hot rolling, and combined rolling is performed with a reverse type hot rolling mill.
- the core material and the skin material are pressure-bonded by the combined rolling, and after the pressure-bonding, a normal aluminum alloy ingot is rolled to a target thickness in the manner of hot rolling.
- Patent Document 1 In order to solve the above-mentioned problems in the production of the clad material, in Patent Document 1, when producing an aluminum alloy clad material, only the surface layer portion of the laminated material is heated to prevent peeling of the clad interface during the laminating rolling. A manufacturing method that can perform pressure rolling at a high pressure reduction rate has been proposed. However, in Patent Document 1, when crimping and rolling is performed under a higher pressure than expected, the mating surfaces are not joined to each other. Therefore, there is a possibility that warpage occurs and the crimping surfaces peel and the clad material cannot be manufactured.
- Patent Document 2 As a method for joining metal materials, rolling is performed by sandwiching an intermediate material interspersed with a metal metal to be joined in a soft metal such as aluminum, which is not dissolved in a matrix in a solid state. There has been proposed a method of heating and pressurizing by means of, extrusion, drawing or the like. In this method, there is a manufacturing limitation that a strong reduction must be applied within a temperature range where the intermediate material melts. Further, elements added to the intermediate material have a low melting point and are not dissolved in the solid state, and it is presumed that only a low melting point metal existing on the surface can be used for bonding. For this reason, the amount added to obtain a sufficient bonding strength is considerably increased, and there are many low melting point metal components remaining at the bonding interface after bonding, and there is a concern that the characteristics of the metal base material may be adversely affected.
- liquid phase diffusion bonding especially when used for large industrial products, it is difficult to optimally control the remaining amount of the insert material that becomes the liquid phase after bonding, and the growth of intermetallic compounds formed at the joints is difficult.

Abstract
Description
液相の生成メカニズムについて説明する。図1に代表的な2元系共晶合金であるAl-Si合金の状態図を模式的に示す。Si濃度がc1であるアルミニウム合金材を加熱すると、共晶温度(固相線温度)Teを超えた付近の温度T1で液相の生成が始まる。共晶温度Te以下では、図2Aに示すように、結晶粒界で区分されるマトリクス中に晶析出物が分布している。ここで液相の生成が始まると、図2Bに示すように、晶析出物分布の偏析の多い結晶粒界が溶融して液相となる。次いで、図2Cに示すように、アルミニウム合金のマトリクス中に分散する主添加元素成分であるSiの晶析出物粒子や金属間化合物の周辺が球状に溶融して液相となる。更に図2Dに示すように、マトリクス中に生成したこの球状の液相は、界面エネルギーにより時間の経過や温度上昇と共にマトリクスに再固溶し、固相内拡散によって結晶粒界や表面に移動する。
アルミニウム合金材の表層には酸化皮膜が形成されており、これによって接合が阻害される。従って、接合においては酸化皮膜を破壊する必要がある。本発明に係るクラッド材の製造方法では、接合時に酸化被膜を破壊するために以下のD-1又はD-2に示すいずれかの方法が採用される。
この方法では、酸化皮膜を破壊する為に少なくとも接合部にフラックスを塗布する。フラックスはアルミニウム合金のろう付で用いるKAlF4やCsAlF4などのフッ化物系フラックス又はKClやNaClなどの塩化物系フラックスが用いられる。これらフラックスは、液相が溶融する前に又は接合温度に至る前に溶融し、酸化皮膜と反応して酸化皮膜を破壊する。
アルミニウム合金材にMgが所定量添加されている場合は、接合部にフラックスを塗布しなくても、酸化被膜が破壊されて接合が可能になる。この場合、真空フラックスレスろう付と同様に、アルミニウム合金が溶融し液相が表層に出てくるときに、アルミニウム合金中より蒸発するMgのゲッター作用によって酸化皮膜が破壊される。Mgのゲッター作用により酸化皮膜を破壊する場合、酸化皮膜の形成を抑制するために、真空中又は上記の非酸化性雰囲気中で接合する。但し、本発明の場合は面接合であるので、乾燥した大気であっても接合可能である。Mgのゲッター作用により酸化皮膜を破壊する為には、本発明では、液相を生成するアルミニウム合金材が0.20mass%以上かつ2.0mass%以下のMgを含有するものとする。0.20mass%未満では、十分なゲッター作用が得られず良好な接合が達成されない。一方、2.0mass%を超えると、表面でMgが雰囲気中の酸素と反応して酸化物MgOが多く生成され接合が阻害される。
Al-Si合金:
Siの含有量が0.40~4.5mass%のものが好適に用いられる。0.40mass%未満の場合、液相率が5.0%~35%となる温度範囲が狭くなり、安定した接合が困難となる場合がある。一方、4.5mass%を超えると、固相線温度=共晶温度で発生する液相の量が35%に近くなり、固相線温度から液相率35%の温度範囲が狭くなって安定した接合が困難となる場合がある。より好ましいSi含有量は、1.2~3.0mass%である。
Cuの含有量が0.70~10mass%のものが好適に用いられる。0.70mass%未満の場合、液相率が5.0%~35%となる温度範囲が狭くなり、安定した接合が困難となる場合がある。一方、10mass%を超えると、強度が高くなり、圧延時に割れが発生して製造できない。より好ましいCu含有量は、1.5~6.0mass%である。
Cuの含有量が0.40~10mass%、Siの含有量が0.30~4.5mass%のものが好適に用いられる。Cuの含有量が0.40mass%未満の場合、液相率が5.0%~35%となる温度範囲が狭くなり、安定した接合が困難となる場合がある。一方、10mass%を超えると、強度が高くなり、圧延時に割れが発生して製造できない。Siの含有量が0.30mass%未満の場合、液相率が5.0%~35%となる温度範囲が狭くなり、安定した接合が困難となる場合がある。一方、4.5mass%を超えると、固相線温度=共晶温度で発生する液相の量が35%に近くなり、固相線温度から液相率35%の温度範囲が狭くなって安定した接合が困難となる場合がある。より好ましいCu含有量は、1.5~6.0mass%であり、より好ましいSi含有量は1.2~3.0mass%である。

表1,2に接合にクラッド材製造に用いた液相を生じる役目を果たすアルミニウム合金材(以下、実施例及び表において「中間層」ともいう)の成分を示す。表3に接合するアルミニウム合金材(以下、実施例及び表において「主層」ともいう)の成分を示す。表1~3には各合金の固相線温度を併記した。固相線温度は、熱力学計算ソフトThermo-Calcによる計算値である。なお、表1~3における各成分「-」は当該元素を含有していない(検出限界未満)ことを意味する。
比較例2、24では、中間層から生成する液相が35%を超えたため、接合が十分になされず、圧延後の層の剥離が起こり、不十分な結果となった。
比較例10では、フラックスを使用する場合の中間層のMg添加量が本発明の範囲外であり、接合時に表面の酸化膜が破壊されず、接合が十分になされず、圧延後の層の剥離が起こり、不十分な結果となった。
比較例21、22では、フラックスを使用しない場合の中間層のMg添加量が本発明の範囲外であり、接合時に表面の酸化膜が破壊されず、接合が十分になされず、圧延後の層の剥離が起こり、不十分な結果となった。
次に3層材以上の多層材の実施例73~77を示す。表6に接合条件および接合率を示す。いずれの実施例でも接合するアルミニウム合金材の溶融はなく、圧延時の各層の剥離もなく、良好に圧延できた。
