One aspect of the disclosure relates to a method of making a part (14) from at least one elemental metal powder. The part (14) has a near-net shape, a part volume, and a part density. The method includes providing a sintered preform (134) having a sintered density (300) and separating a portion (134A) from the sintered preform (400). The portion (134A) has a portion volume exceeding the part volume and a portion shape different from the near-net shape of the part (14). The method also includes thermally cycling the portion (134A) for a thermal-cycling time period at a thermal-cycling pressure while superplastically deforming the portion (134A) to form the part having the near net shape and the part density (500).
