A sintered gear of annular shape which has a composition including a metal, has a plurality of pores in a surface thereof, and has a relative density of 93% or more and 99.5% or less.

A method for manufacturing a sintered component includes a step of making a green compact having a relative density of at least 88% by compression-molding a base powder containing a metal powder into a metallic die, a step of machining a groove part having a groove width of 1.0 mm or less in the green compact by processing groove with a cutting tool, and a step of sintering the green compact in which the groove part is formed after the step of forming the groove part.

A method of producing a patterned composite metal plate includes a) providing at least two different metal and/or metal alloy powders, b) filling a container, b1) with the powders in different individual layers, or b2) making a three dimensional non-solid body of one of the powders, inserting said body in the container and filling the cavities in and around the said body completely with the other powder, c) sealing and evacuating the container, d) subjecting the container to hot isostatic pressing, e) optionally subjecting the consolidated body to hot deformation to form an intermediate body having a thickness of 50 to 200 mm, f) hot rolling the intermediate body in two perpendicular directions in order to form a plate, and optionally one or more of g) cold rolling the hot rolled plate to form a cold rolled plate h) slitting the plate and i) etching the plate.

An apparatus includes one or more layers of material printed by a three-dimensional (3D) printer. The one or more layers cool and solidify to form an object after being printed by the 3D printer. At least one of the one or more layers includes greater than 50% metal. The apparatus also includes a first temperature sensor in contact with the object. The first temperature sensor measures the temperature of the material while the object is being printed by the 3D printer, after the object has been printed by the 3D printer, or both.

An object printed by a three-dimensional (3D) printer includes a plurality of layers of material printed by the 3D printer. The layers of material bond together to form the object as the layers of material cool and solidify after being printed by the 3D printer. The object also includes a temperature sensor placed in contact with one or more of the layers when the layers of material are being printed by the 3D printer. The temperature sensor remains in contact with the object after the layers of material cool and solidify to form the object. The temperature sensor is configured to measure a temperature of the object after the layers of material cool and solidify to form the object.
