One or more ductile metal inserts may be selectively incorporated into articles of limited ductility, including metal castings and molded polymers. The inserts are positioned at joint locations for joining of the article to other articles using self-piercing riveting (SPR). The inserts are of suitable ductility, thickness and strength to receive and retain self-piercing rivets and enable a strong riveted joint between the article and a second article. In an embodiment the articles are magnesium alloy castings formed by any of sand casting, die casting and semi-solid metal casting. The chemical composition of the insert may be informed by the anticipated corrosive environment of the joint and the casting temperature of the magnesium alloy. For magnesium alloy castings which may be exposed to corrosive environments, aluminum alloy inserts are preferred.

A laminated member as a laminate of a plurality of alloy ribbons is used. The laminated member has a side surface with a fracture surface. A laminated body as a laminate of the laminated member is used. A motor that includes a core using the laminated body is used. A method for manufacturing a laminated member is used that includes: fixing a plurality of amorphous ribbons to one another in a part of layers of the amorphous ribbons after laminating the amorphous ribbons; and punching a laminated member by cutting the laminate of the amorphous ribbons at a location that excludes the portion fixing the amorphous ribbons in the laminate.

A pin comprising a conical body having a central axis and a cross-sectional area that decreases with distance from a first end to a second end. A coating applied to the conical body has a melting temperature that is lower than a melting temperature of the conical body. The coating melting temperature is lower than a friction temperature and the body melting temperature is higher than the friction temperature. The friction temperature is achieved at an interface of the pin and a component when the pin is forcibly positioned into the component to repair a defect. The coating comprises a material having a first tensile strength value of a bond formed between the conical body and the component in response to softening and rehardening of the coating.

A process of fabricating a shield, a process of preparing a component, and an erosion shield are disclosed. The process of fabricating the shield includes forming a near-net shape shield. The near-net shape shield includes a nickel-based layer and an erosion-resistant alloy layer. The nickel-based layer is configured to facilitate secure attachment of the near-net shaped to a component. The process of preparing the component includes securing a near-net shape shield to a substrate of a component.
