For a given extrusion ratio, mechanical properties of alloy wire decrease and conductivity increases with increase of on-line solution temperature and ageing temperature.
当挤压比一定时，随着在线固溶温度与时效温度的升高，线材的力学性能下降，导电性能升高。

The results indicate that natural ageing after solution heat-treatment leads to the effective increasement of the comprehensive mechnical properties.
通过固溶后自然时效处理，可有效地提高合金的综合力学性能；
