Deformed Fiber Strengthened High-Strength and High-Conductivity Alloy

摘要:

通过对不同成分的Cu-Ag合金进行大形变量拉伸及热处理，制成了具有高强度、高电导率的纤维增强复合材料，合金线材的抗拉强度达到了1．1GPa、电导率为80％IACS。研究了合金成分、形变及热处理在这一过程中对Cu-Ag合金力学性能、电学性能的影响。并对其强化机理进行了讨论。

Abstract:

The alloy Cu-Ag with high strength and conductivity is studied in this paper. The tensile strength of 11 GPa and the conductivity of 80% international annealing copper standard (IACS) for the alloy have been obtained. The influences of deformation, heat treatment and alloying constituent on comprehensive properties of the alloy are discussed, and the strengthening mechanism is also analyzed.
