Abstract
Systems and methods for forming near net-shape metal parts from binderless metal powder are disclosed. Systems include a mold die that defines a die cavity and may include one or more ultrasonic transducers operatively coupled to the mold die. Systems may be configured to introduce binderless metal powder into a die cavity and/or to compact the binderless metal powder within the die cavity. Methods include introducing binderless metal powder into a die cavity of a mold die and compacting the binderless metal powder within the die cavity to form a green part within the die cavity. The binderless metal powder may include spheroidal metal particles and angular metal particles. The methods may further include separating the green part from the mold die and sintering the green part, after separating, to form a sintered near net-shape metal part.
