    Abstract: One aspect of the disclosure relates to a method of making a part from at least one elemental metal powder. The part has a near-net shape, a part volume, and a part density. The method includes providing a sintered preform having a sintered density and separating a portion from the sintered preform. The portion has a portion volume exceeding the part volume and a portion shape different from the near-net shape of the part. The method also includes thermally cycling the portion for a thermal-cycling time period at a thermal-cycling pressure while superplastically deforming the portion to form the part having the near net shape and the part density.

    Abstract: A method for consolidating a pre-form made of powder, comprising: (a) placing the pre-form between smart susceptors; (b) heating the smart susceptors to a leveling temperature by applying a varying low-strength magnetic field having a magnetic flux that passes through surfaces of the smart susceptors; (c) applying consolidation pressure to the pre-form at least during a time period subsequent to the temperature of the smart susceptors reaching the leveling temperature; and (d) while consolidation pressure is being applied, applying a pulsed high-strength magnetic field having a magnetic flux that passes through a surface of the pre-form. The strength and pulse rate of the high-strength magnetic field are selected so that the crystallographic phase of the pre-form will rapidly oscillate at a substantially constant temperature. The pulsed high-strength magnetic field is applied sufficiently long that superplasticity of the pre-form is attained during phase oscillation.
