METHODS OF MAKING PARTS FROM AT LEAST ONE ELEMENTAL METAL POWDER |
摘要 |
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. |

1. A method of making a part from at least one elemental metal powder, the part having a near-net shape, a part volume, and a part density, the method comprising:
providing a sintered preform having a sintered density; separating a portion from the sintered preform, the portion having a portion volume exceeding the part volume and a portion shape different from the near-net shape of the part; and 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. |
