合される。An aluminum chamber is generally used as a vacuum chamber of a particle accelerator such as a synchrotron, but a stainless chamber may be partially used. In this case, it is necessary to connect the aluminum chamber and the stainless chamber with a dissimilar material joint. An example in which this dissimilar material joint is realized by flange joining using the clad material of FIG. 2 is shown in FIG. One of the vacuum chambers 24 in FIG. 4 is composed of the stainless steel chamber 20, and the other is composed of the aluminum alloy chamber 22. A flange 26 made of a clad material is joined to the end of the stainless chamber 20 by welding 28. The flange 26 is obtained by cutting the clad material 14 shown in FIG. 2 as shown by a chain double-dashed line 26. A flange 30 made of a high-strength aluminum alloy material (for example, A2219) is joined to the end of the aluminum alloy chamber 24 by welding 32. Flange 2
By connecting 6 and 30 with bolts and nuts 34, the chambers 20 and 22 made of different materials are flange-joined.

An enlarged view of the seal portion of FIG. 4 (a) is shown in FIG. 4 (b). A void 38 is formed in the inner peripheral portion of the abutting surfaces 35, 36 of the flanges 26, 30 and edges 40, 42 are formed in a ring shape. A ring-shaped metal gasket 50 is housed in this space 38, and the bolts and nuts 34 are tightened with a predetermined tightening torque, whereby the edges 40 and 42 are bited into the metal gasket 50 by a predetermined amount and vacuum sealed.

なうことができる。As shown in FIG. 4 (c), when the edges 40 and 42 of the flanges 26 and 30 are made to fit into the metal gasket 50 for vacuum sealing, if the edges 40 and 42 are soft, the edges 40 and 42 will be crushed and the seal will be generated. The sex becomes worse. When the edges 40 and 42 are crushed, it is difficult to regenerate (processing the edges 40 and 42 and sharpening again), and in some cases, the entire flanges 26 and 30 must be replaced. Therefore, when such a seal structure is used, the abutting portions of the flanges 26 and 30 need to be made of A2219T87 or the like, which has high strength among high-strength aluminum alloy materials. This high strength aluminum alloy material A2219T
87 is a solution treatment of A2219, then cold working and then artificial age hardening treatment, which has high strength. If this is used for the abutting portion of the flanges 26, 30, the edges 40, 42 will not be crushed and the metal will not be crushed. Since the gasket 50 can be easily inserted, a good vacuum seal can be performed.

3 is composed of A2219T87 or the like, there is a problem that the high-strength aluminum alloy material 10 is cracked or cracked by the impact in the step (10) of explosion-bonding in FIG. 3 or the step (11) of strain relief by pressing or the like. In an ultra-high vacuum member, leaks may occur due to minute cracks and cracks and the degree of vacuum may deteriorate, so cracks and cracks must be reliably eliminated.

ができる。[Function] The high-strength aluminum alloy material that has been naturally aged after the solution heat treatment has a weaker strength than the high-strength aluminum alloy material that has been artificially age-hardened after the solution heat treatment such as A2219T87, but has a larger absorbed energy against impact. Therefore, it is resistant to the impact due to the bombardment and the strain relief treatment, and it is possible to prevent the occurrence of cracks and cracks. Further, since the artificial age hardening treatment is performed after the bombardment and the strain relief treatment, the strength of the high strength aluminum alloy material can be increased. This makes it possible to manufacture a clad material having a high-strength high-strength aluminum alloy material without cracks or cracks. For example, when the clad material is used for a dissimilar material joint of the vacuum chamber 24 shown in FIG. Metal gasket 50 without crushing 42
It can be made difficult to insert, and good sealing properties can be obtained.

T4 (or T3)). A2219T4 is a solution solution-treated and then naturally aged (A2219T3 is a solution-treated, cold-worked and naturally-aged)
Absorbed energy against impact is higher than A2219T87. (10) Explode. (11) Remove the distortion with a press or level roller. Figure 5
Shows the absorbed energy of A2219T4 and A2219T87, which is about 3.5kgf ・ m.
If it is smaller than that, cracks or cracks occur. According to this, since the absorbed energy of A2219T87 is smaller than 3.5 kgf · m, cracks or cracks may occur, but since the absorbed energy of A2219T4 is larger than 3.5 kgf · m, cracks or cracks may occur. Absent. Therefore, steps (10) and (11)
It is possible to prevent the high-strength aluminum alloy material 10 from cracking or cracking due to the bombardment or strain removal treatment. (12) For example, artificial aging treatment is performed by heating at a temperature of 185 to 190 ° C. for 9 hours. As a result, the strength of the high-strength aluminum alloy material 10 is increased, and the strength equivalent to A2219T6 is obtained. (13) The product is completed.
