GRADIENT SINTERED METAL PREFORM |
| 摘要 |
A method of forming a metal component with two and three dimensional internal functionally graded alloy composition gradients includes forming the component by a powder based layer-by-layer additive manufacturing process. The areal composition distribution of each powder layer is determined by simultaneously depositing different powders and powder mixtures through a mixing valve attached to a single nozzle during powder deposition. The layers are then sintered with a directed energy source to form a forging preform. The preform is then forged to form a component. |

1. A method of forming a metal component with two and three dimensional internal alloy compositional gradients comprises:
forming the component by a powder-based layer-by-layer additive manufacturing process; controlling the areal composition of each powder layer by depositing different powders to different areas through a single powder deposition nozzle during powder deposition; and sintering the layer with a directed energy source to form the component. |
