The present invention relates to an apparatus and a method for manufacturing a soft magnetic composite using ultrasonic vibration and a soft magnetic composite manufactured using the ultrasonic vibration. More specifically, the present invention relates to the apparatus for manufacturing a soft magnetic composite using ultrasonic vibration including: a die that has a putting-in space as an open space in which a powder material is put; a punch set that is inserted into the putting-in space and presses the powder material; an ultrasonic vibration applying unit including ultrasonic vibrators which are arranged along a circumference of an outer die surface of the die and are provided to come into contact with the die; a main body that is positioned below the die and is formed to slide around the die toward an outer circumference; and a control unit that controls a frequency of the ultrasonic vibrators depending on a degree of pressure of the punch set, a method for manufacturing a soft magnetic composite using ultrasonic vibration, and a soft magnetic composite manufactured using the same.

The present invention concerns a pressed cutting tool comprising a variable core diameter, a mold and a method for producing the cutting tool by pressing. Said cutting tool preferably comprises a shaft and a part comprising one or more helical flutes, wherein low points or lines in said flutes define the shape of said core. In a preferred embodiment, said core is conical. In a preferred embodiment, said cutting tool is an end mill and/or a drill.

A thermoelectric conversion element of the present disclosure includes a thermoelectric conversion layer, a first metal layer, a second metal layer, a first joining layer, and a second joining layer. At least one of the first joining layer and the second joining layer includes a second alloy. A content of Mg in the second alloy is 84 atm % or more and 89 atm % or less, a content of Cu in the second alloy is 11 atm % or more and 15 atm % or less, and a content of an alkaline earth metal in the second alloy is 0 atm % or more and 1 atm % or less.

The present disclosure generally relates to powder packing for additive manufacturing (AM) methods and systems. Conventional powder packing methods are manual and non-standardized, and they result in operator fatigue and potentially product inconsistencies. Powder packing according to the present disclosure improves standardization and reduces turnaround time, with the potential to lower the cost of AM.

A process and apparatus of producing a product having a wrought structure. The process comprises the step of: applying heat and a compressive load simultaneously to an application area of a cold spray deposition preform to transform the comprising consolidated particle structure into a wrought structure, the compressive load being applied laterally to the application area. The application of compressive load and heat to the application area raises the temperature of the material of the preform in the application area to between the recrystallisation temperature and the melting point of the material.

A sintered metal connecting rod (10) includes as an integrated body, a large end portion (11), a small end portion (12), and a stem portion (13). In the sintered metal connecting rod (10), division marks (14a, 14b) of a molding die by a compression molding are formed between the large end portion (11) and the stem portion (13) and between the small end portion (12) and the stem portion (13) on one of front and back surface (11c to 13c) in which the through-holes (11a, 12a) are formed, respectively. The large end portion (11) and the stem portion (13) have a density difference of 4% or less, and the small end portion (12) and the stem portion (13) have a density difference of 4% or less.
