A method for manufacturing a dissimilar metal joint product includes: spraying a metal powder capable of being joined to a steel material to at least a part of a surface of an aluminum or aluminum-alloy material at a low temperature and at a high speed to form a coating thereon; disposing the aluminum or aluminum-alloy material and the steel material such that the coating and the steel material face each other; and performing brazing using a brazing material or welding using a welding material between the coating and the steel material.

A vehicle body assembly is described herein, including a first structural component and a second structural component. The first structural component may be a roof component or a side panel, and include a first part including a first metal and a second part including a second metal different than the first metal. The second part is formed on a peripheral edge portion of the first part and defines a mounting flange for the first structural component. The second part is joined to the first part via an ultrasonic additive manufacturing (UAM) interface. The second structural component is including the second metal and is joined to the second part at the mounting flange via a resistance spot weld (RSW) joint.

The disclosure provides an aluminized composite including a base material. The aluminized composite may also include a diffusion layer disposed over the base material. The aluminized composite may further include an aluminum material disposed over the diffusion layer.

A method of joining a first piece of an automotive component that is made from a first material to a second piece of the automotive component that is made from a second material includes machining a fay surface onto each of the first and second pieces of the automotive component, cleaning the fay surfaces of each of the first and second pieces of the automotive component, placing a metal filler between the fay surfaces of the first and second pieces of the automotive component, holding the first and second pieces together with the metal filler positioned between the fay surfaces of the first and second pieces, and passing an electric current through the first piece, the metal filler and the second piece to melt the metal filler and weld the first piece to the second piece.

A method of welding a component made from a ferrous alloy to a component made from an aluminum alloy includes machining and cleaning a fay surface on the ferrous alloy component, machining and cleaning a fay surface on the aluminum alloy component, depositing a layer of copper alloy material onto the fay surface of the ferrous alloy component, forming a weld groove on at least one of the layer of copper alloy material deposited on the fay surface of the ferrous alloy component and the fay surface of the aluminum alloy component, and laser welding the layer of copper alloy deposited on the fay surface of the ferrous alloy component and the fay surface of the aluminum alloy component to one another.

There is provided a method of manufacturing a washer capable of suppressing reduction in a sliding area, which includes: a preparing step of preparing a panel-shaped member N; a cutting step of cutting the panel-shaped member N with a laser L2 to thereby obtain a longitudinal member N1; and a forming step of obtaining an arc-shaped washer by using the longitudinal member N1. The panel-shaped member N has an equal width to a longitudinal width of the longitudinal member N1. The cutting step is a step of cutting the panel-shaped member N from one end to the other end in a width direction to thereby obtain the longitudinal member N1 and the forming step is a step of deforming the longitudinal member N1 into an arc shape so that cut faces of the longitudinal member N1 form an outer peripheral face and an inner peripheral face.

A multi-material component joined by a high entropy alloy is provided, as well as methods of making a multi-material component by joining materials with high entropy alloys to reduce or eliminate liquid metal embrittlement (LME) cracks.

A method of creating a clad metal part is provided. The method includes explosion bonding a plate comprised of a base layer and an interlayer. The explosion bonded plate is then cut into bars which are roll bonded with a clad layer. Ultimately a part is fabricated from the roll bonded bar. The solution enables parts to have material combinations and resulting physical properties more optimal for an application than a single bonding process.

A dissimilar metal article may include a first metallic component including a first metal material, a second metallic component comprising a second metal material, and a transition joint provided between and bonding a first metallic component first end surface to a second metallic component first end surface. An additive flow material may be further provided to the dissimilar metal article to strengthen the joint between the first metallic component and the second metallic component.

A multi-material boss, configured for fastening of a fastener thereto, being a feature of a the cast part, comprising a boss cylinder, an augmenting cylinder, and a filler metal layer is provided. The boss cylinder is made of the same material as the die cast part having a first hardness, and has a first interior. The augmenting cylinder is made of an augmenting material having a second hardness, is fixedly secured in the first interior of the boss cylinder, and has a second interior defined by a second cylindrical shaped wall, a base rim, and a second opening. The second hardness is greater than the first hardness. The fastener is fastened to the multi-material boss via the second opening of the augmenting cylinder having the higher liquidus temperature and greater hardness.
