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.

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 metal sheet for press forming has a shape such that a boundary position between the region corresponding to the curved portion and an other region in the region corresponding to a curved portion is rotationally displaced in-plane around a rotational center set at a position on a curved recessed side rather than a position corresponding to a ridge line between a top sheet portion and a vertical wall portion on the curved recessed side, in a direction in which a line length of an outer edge of a position to be formed into the flange portion on a curved protruding side in the region corresponding to a curved portion approaches a line length of an outer edge of the flange portion on the curved protruding side in the press-formed component shape.

Billets and methods for manufacturing them are disclosed. The billets include a cladding member including an alloy selected from the group including stainless steel, nickel-chrome, nickel-copper, and copper-nickel alloys, and a steel body that is positioned so that it has an interface with the cladding member, the steel body having a formation in which the scavenging metal is located and elements being provided for separating the scavenging metal from the cladding member at the interface.

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.
