摘要：

Fibrous chromium and molybdenum were fabricated by cold working two-phase alloy ingots of Cu-Cr and Cu-Mo. Since the chromium and molybdenum are precipitated and grow as monocrystals in the copper matrix, there are no problems with grain boundaries which are responsible for the brittleness of polycrystalline group VIa metals. The chromium and molybdenum fibres can easily be removed from the composite by selectively etching away the copper matrix. Chromium fibres can be obtained almost irrespective of the purity of the starting materials. The composite of copper reinforced with chromium fibres exhibits high mechanical strength and electrical conductivity. © 1990.
