Mourning and memorial jewelry items and methods for manufacturing the same are described. The methods utilize metal implant materials from deceased individuals to create items of jewelry for retention and use by survivors. The overall method includes a planning process that discerns the type of metal implants available and identifies the type of jewelry desired. The planning process establishes a preferred method for manufacture, based on the size and shape of the available implant objects, as well as the desired item of jewelry. The jewelry items are either unitary pieces of jewelry or jewelry stones. The preferred method for transforming the implant object into the item of jewelry will involve machining, annealing or forging, and/or melting and casting. The preferred method is implemented and results in either the finished item of jewelry or a metallic stone that may be set into a jewelry setting.

The forging apparatus includes: a fixed punch 21 in which a tapered part 21a for molding the diameter enlarged part is formed; a die 30 arranged so as to surround an outer periphery of the fixed punch 21; and a movable punch 10 that is arranged above the fixed punch 21 so as to be opposed to the fixed punch 21. The die 30 is floatingly supported and includes a protruding part 33a for molding the groove on an inner peripheral surface thereof, and when the movable punch 10 is lowered, an annular blank 40 set between the fixed punch 21 and the die 30 is pressed, and the annular member is molded, the die 30 is lowered along with the movable punch 10, and the groove is molded on the outer peripheral surface of the diameter enlarged part while molding the diameter enlarged part.

Provided is a production method, including a first preforming process, a second preforming process, a final preforming process, and a finish forging process. In the first preforming process, regions to be a pin and a journal are pressed respectively from a direction perpendicular to an axial direction of the billet, thus reducing cross sectional areas of each region and forming a plurality of flat parts. In the second preforming process, the first preform is pressed in the pressing direction, which is a direction perpendicular to decentering direction of a region to be a second pin. In the final preforming process, the second preform is pressed from a direction perpendicular to an axial direction of the second preform, and further a region to be a counterweight and a region to be a crank arm integrally including a counterweight are pressed in the axial direction of the second preform.

The present invention discloses a cold additive and hot forging combined forming method of amorphous alloy parts. The present invention belongs to the field of cold additive manufacturing technology and thermoplastic forming of amorphous alloy, and more particularly relates to a cold additive and hot forging combined forming method of amorphous alloy parts, the method comprising: (1) making amorphous alloy powder into a pre-forging blank by the micro-jetting and bonding 3D printing technology; and (2) placing the pre-forging blank in the step (1) in a closed forging die to perform hot closed-die forging so as to obtain an amorphous alloy part, wherein the contour size and shape of the pre-forging blank are designed according to the contour size and shape of the inner cavity of the closed forging die; and an exhaust hole is provided in the closed forging die such that gas generated by gasification or decomposition of the binder at a hot die forging temperature is discharged through the exhaust hole in the closed forging die. In the present invention, a bulk amorphous alloy part with a large size and a complex shape can be prepared by the cold additive and hot forging combined forming method.

In the second preforming process, the first preform is pressed in the pressing direction, which is a width direction of the flat parts. In the final preforming process, the second preform is pressed from a direction perpendicular to an axial direction of the second preform, and further a region to be a counterweight and a region to be a crank arm integrally including a counterweight are pressed in the axial direction of the second preform.

Aluminum wheels include a rim and a disc having a mounting portion. The mounting portion includes an inner mounting face and an outer mounting face. The mounting portion also includes a coarse grain region and a fine grain region. The coarse grain region can be adjacent, and at least partially form, one of the inner mounting face or the outer mounting face. The coarse grain region includes aluminum alloy grains of a first average grain length that is greater than 1 mm. The fine grain region extends between the coarse grain region and the other of the inner mounting face or the outer mounting face. The fine grain region includes aluminum alloy grains of a second average grain length that is less than 0.5 mm.

Aluminum alloys described herein include silicon, iron, copper, manganese, magnesium, and chromium. In various implementations, the aluminum alloys also include one or more of zinc and titanium. Typically, a total amount of iron and manganese in the aluminum alloys is no less than 0.28% by weight and no greater than 0.45% by weight, and the grains in the aluminum alloys have an average grain length of no greater than 6 mm. Aluminum alloy billets can be forged for wheel production at selected temperatures.

A thick steel plate is provided by heating a continuously-cast slab, hot forging the continuously-cast slab using opposing dies having respective short sides differing such that when a short side length of a die having a shorter one of the short sides is taken to be 1, a short side length of a die having a longer one of the short sides is 1.1 to 3.0, allowing cooling to obtain a steel raw material, reheating the steel raw material, performing hot rolling of the steel raw material including at least two passes carried out, allowing cooling to obtain a thick steel plate, reheating the thick steel plate to at least the Ac.sub.3 temperature and no higher than 1050 C., rapidly cooling the thick steel plate to 350 C. or lower, and tempering the thick steel plate at at least 550 C. and no higher than 700 C.

A handcuff of the present invention includes a first forged cheek frame half including a first cheek arm and a first lockset cavity portion and a second forged cheek frame half including a second cheek arm and a second lockset cavity portion. When the first and second forged cheek frame halves are combined, the first and second lockset cavity portions combine to form a lockset cavity between the first and second cheek frame halves. A bow having outwardly facing teeth along a portion of the bow is rotatably fastened to the first and second cheek arms. A removable lock mechanism disposed within the lockset cavity, the lock mechanism comprising movable pawls corresponding to the teeth, wherein the pawls releasably engage the teeth when the bow is rotated into engagement with the lock mechanism.
