| However, conventional ingot metallurgy methods, such as stir casting, lead to rough initial primary Si phase and ceramic particle aggregation, that is limits the farther improving the properties. Spray deposition (an approaches to combine rapid solidification and near-net-shape fabrication) can be an effective to produce pre-forms in a single-step operation directly from a molten alloy. |
