5. 性能表 Performance table

弥散强化铜的性能来源于加入的氧化铝。氧化铝颗粒的尺寸仅为3～12纳米，颗粒间距约为50～100纳米，其热稳定性*好，甚至在接近铜熔点的温度下仍然能保持去原来的粒度和颗粒间距；弥散相的加入量只占基体*小的体积分数，几乎不影响基体铜铝固有的物理化学性质；因此，其软化温度高达930℃，同时导电和导热以及硬度和强度都能保持得很好。

The performance of dispersion-reinforced copper is derived from the addition of alumina. The size of the alumina particles is only 3 to 12 nanometres and the particle spacing is about 50 to 100 nanometres, which is thermally stable*, even at temperatures close to the melting point of copper. as well as hardness and strength are well maintained.
