| 摘 要： | 利用自制的热型连铸设备生产了单晶铜棒材，对其铸态、冷加工态、退火态的力学性能与电学性能进行了系统的测试与研究。结果表明：和多晶铜相比，单晶铜在铸态时具有良好的塑性和较低的电阻率，并具有优异的室温延展性，其延伸率可达6100％以上；冷拉拔加工后单晶铜表现出更大的加工硬化现象，但采用合理的退火工艺可使其加工硬化得到缓解。

| Abstract: | The mechanical and electrical properties of as-cast, as-drawing and as-annealing single crystal copper prepared with self-made heated mould continious casting apparatus were studied. Compared with polycrystalline Cu, the as-cast single crystal copper shows better plasticity and extensibility, and has a lower electricity resistance. Its elongation of cold rolling can reach 6100% without any cracks in the edges. The single crystal copper exhibits more serious work hardening in wiredrawing. The plasticity and electricity resistance of as-drawing single crystal copper can be resumed after being annealed. |
