Abstract

The invention relates to a graphene-carbon nano tube composite modified copper-iron alloy and a preparation method thereof. The preparation method comprises the following steps: first preparing graphene and a carbon nano tube-iron nano composite material, then mixing the graphene and the carbon nano tube-iron nano composite material with copper powder and iron powder, preparing a graphene-carbon nano tube composite modified copper-iron alloy material through SPS, and mixing the material with anode copper, carrying out vacuum melting to obtain a graphene-carbon nano tube composite modified copper-iron alloy ingot; and grinding the alloy ingot, carrying out hot forging and after-forging grinding, thermally rolling the ingot, and slowly reducing the heating temperature to room temperature to obtain the graphene-carbon nano tube composite modified copper-iron alloy. As a graphene-carbon nano tube is uniformly dispersed in the alloy, the copper-iron alloy is relatively high in compactness; and furthermore, compared with a pure copper-iron alloy, the graphene-carbon nano tube composite modified copper-iron alloy has the advantages that as the graphene and a carbon nano tube are high in mechanical property, the prepared copper-iron alloy is higher in Rockwell hardness and heat conductivity and has a very wide application prospect in all fields.

Description

technical field [0001] The invention belongs to the field of copper alloys, and particularly relates to a preparation method of a graphene-carbon nanotube composite modified copper-iron alloy. Background technique [0002] Copper alloys refer to alloys with copper as the main component. The most well-known types of copper alloys are bronze (copper is the main component, tin is the secondary) and brass (copper is the main component, and zinc is the secondary). With the development of science and technology , copper-iron alloys have gradually attracted people's attention. It is mentioned in CN201510459015.9 that some characteristics of Cu-Fe alloys can be predicted from the knowledge of metal materials: (1) The melting point should be higher than Cu and lower than Fe. If it is used as a vacuum electrical contact material to replace Cu alloy, it can improve its arc ablation resistance; (2) Pure copper and pure iron have good ductility, so Cu-Fe alloy should also have this perfo...
