| titleOfInvention | A kind of preparation method using vacuum consumable arc-melting CuFe alloy material |
| abstract | The invention discloses a kind of preparation methods using vacuum consumable arc-melting CuFe alloy material, the following steps are included: the mixing of (1) raw material: material composition and its weight percent are as follows: Cu70%-30%, Fe30%-70%, proportionally weigh required raw material, it is mixed in batch mixer, mixing time 2-4h；(2) it suppresses: mixed mixed powder being packed into gum cover and first carries out mechanical shock 30-60s, then material 3-6min, then reversed pier material 3-5 times are rolled, the mixed powder handled well is suppressed using cold isostatic pressing process, pressure is 150~300MPa, dwell time 3-10min；(3) it is sintered: the consutrode suppressed being packed into vacuum sintering furnace and be sintered, sintering maximum temperature control is at 800 DEG C -1080 DEG C, soaking time 30-240min, vacuum degree > 5pa；(4) melting: sintered consutrode being packed into vacuum consumable arc-melting furnace and carries out melting, and melting electric current is 1000-4000A.Gas content of the present invention is low, field trash is few and structural constituent is uniform, the macroscopic views, microdefect such as no Cu, Fe enrichment. |
