A non-magnetic member, a first magnetic member and a second magnetic member are prepared. The first magnetic member and the second magnetic member are connected to the non-magnetic member. Then, a first bonding portion which bonds the non-magnetic member and the first magnetic member to each other, and a second bonding portion which bonds the non-magnetic member and the second magnetic member to each other are formed. A hot isostatic pressing process is performed to the non-magnetic member, the first magnetic member and the second magnetic member to establish diffusion-bond. Thereafter, the non-magnetic member, the first magnetic member and the second magnetic member are hollowed, and the first bonding portion and the second bonding portion are removed. Thereafter, the non-magnetic member becomes a non-magnetic body, the first magnetic member becomes a first magnetic body, the second magnetic member becomes a second magnetic body and a sleeve is obtained.

The present disclosure provides methods for preparing an extruded product from a solid billet. The methods can include providing an as-cast billet for extrusion; applying a simultaneous rotational shear and axial extrusion force to the as-cast billet to plasticize the as-cast billet; and extruding the plasticized as-cast billet with an extrusion die to form an extruded product. Methods for preparing extruded products from billets can also include: providing a billet for extrusion; while maintaining a majority of the billet below 100° C., applying a simultaneous rotational shear and axial extrusion force to one end of the billet to plasticize the one end of the billet; and extruding the plasticized one end of the billet with an extrusion die to form an extruded product. Methods for preparing an extruded product from a billet can also include providing a billet for extrusion; applying a simultaneous rotational shear and axial extrusion force to the billet to plasticize the billet; extruding the plasticized billet with an extrusion die to form an extruded product; and artificially aging the extruded product for less than the ASTM recommended amount of time.

The device includes a laser beam generator, a laser scanner and a linear or matrix-shaped first sensor arrangement with first individual sensors of an identical first sensitivity and at least one identical linear or matrix-shaped second sensor arrangement of second individual sensor, which is arranged with an offset to the first sensor arrangement of first individual sensors, and the second individual sensors have an identical second sensitivity which differs from the first sensitivity.

The concepts described herein provide a method, system, and apparatus for joining, via welding, first and second members fabricated from an aluminum alloy including aluminum, zinc, and manganese, such as 7000-series aluminum alloys, and a resultant workpiece. A junction is formed by a first member being disposed contiguously to a second member. A welding machine generates a weld pool at the junction that includes liquified aluminum alloy. An ultrasonic transducer directs ultrasonic energy in proximity to the weld pool. In some embodiments, an electro-magnetic transducer directs electro-magnetic energy in proximity to the weld pool. The first member is fused to the second member at the junction upon solidification of the weld pool.

Provided are a joint component formed with fine recessed portions so that degradation of the flatness of a metal base body, such as a core, to which a joint object such as a friction member is joined can be reduced, a multiplate clutch device including the joint component, and a joint component manufacturing method. At a friction plate (200) as the joint component, many fine recessed portions (204) are formed at a joint surface (203) as a portion of a core (201) joined to friction members (207). The joint surface (203) is formed in a circular ring shape along a peripheral direction of the core (201), and is formed with a flatness of equal to or less than 0.15 mm. The fine recessed portions (204) are formed at the joint surface (203) such that adjacent ones of the fine recessed portions (204) do not overlap with each other and a formation density per unit area (Ua) at the joint surface (203) is uniform. The fine recessed portions (204) are formed as laser processing marks formed at the core (201) by irradiation with laser light L.
