| 中文摘要: |
| 借助DMIRM金相显微镜、CMT5504微机控制万能试验机和HVS-10数显维氏硬度计等设备，研究了NB-109合金的铸态、加工态及退火态的组织、力学性能及其变化规律.铸态金相组织显示几乎全为α相，为选择冷轧开坯的加工工艺提供了必要的前提条件；为了破坏铸态组织、消除形变织构，获得具有理想组织的成品带材，必须同时具备足够大的冷加工率（约90%）、配合恰当的中间退火温度制度，这是研究的重中之重.根据该材料的特性制备出了具有优异性能的NB-109合金铜带，成功开发出了一种基本与锡磷青铜相同且性能优于锡磷青铜的NB-109合金铜带制备工艺. |

| We investigated NB-109 alloy's casting,cold working state and annealing state's microstructure property,mechanical property and its variation by DMIRM metalloscope,CMT5504 microcomputer control electron universal testing machines and HVS-10 digital display vickers hardness tester.Casting metallographic structure showed that the matrix was almost α phase,which provided the necessary precondition for cold knobbling fabrication technology.In order to destroy casting microstructure,eliminate the deformation texture and attain optimal microstructure of finishing belt,we must design enough cold rolling rate up to 90 percent,meanwhile,coordinate with the appropriate intermediate annealing temperature,which was a priority for all in the paper.Thus,according to the character of NB-109 material,the NB-109 alloy strip with excellent performance was prepared,the fabrication technology was successfully developed that was the same as tin-phosphor bronze's basically,which had more excellent performance particularly than tin-phosphor bronze. |
