| 中文摘要: |
| 铂银合金是一种性能优异的弹性材料，Pt-25Ag合金窄薄带作为某型号悬丝支承加速度计的悬丝材料，由于Pt-25Ag合金加工极其困难、性能不稳定，严重影响了加速度计的质量和供货进度。为解决Pt-25Ag合金加工中存在的问题，通过比较水冷铜模、定向凝固、特殊凝固法3种方法制备的Pt-25Ag铸锭组织，用特殊凝固方法能够解决Pt-25Ag合金加工困难的技术难题，实现Pt-25Ag窄薄带悬丝材料的稳定批量生产，满足型号使用要求。 |
| 英文摘要: |
| Pt-Ag alloy is a kind of elastic material with excellent properties, it’s widely used as suspension wire in electrotechnical instrument and accelerometer of inertial navigation system. Pt-25Ag thin strip is used as suspension wire of pendulous accelerometer in some model weapon. Because it’s very difficulty to produce Pt-25Ag alloy wire, the property and supply period of accelerometer were affected seriously. In order to solve the technical problem of producing Pt-25Ag alloy, the cast microstructure of Pt-25Ag alloy prepared with water-cooled copper mold, directional solidification and a special solidification method was studied. The producing problem can be solved completely with the special solidification method. By the new method, steady and mass production of Pt-25Ag thin strip suspension was realized, and operating requirement of some model weapon can be satisfied. |
