Abstract

The invention discloses a method for preparing a CuFe alloy material with different Fe contents by adopting vacuum induction smelting, and belongs to the technical field of nonferrous metal alloys. The method mainly comprises the following steps of proportioning, charging, vacuumizing, smelting, casting and discharging from a furnace. According to the method, the CuFe alloy is prepared by adoptinga vacuum induction melting method, wherein the Fe element is added in the form of a CuFe mother alloy, the CuFe alloy prepared through the method has the advantages of compact structure, few pores and inclusion, and no macroscopic and microscopic segregation and other defects.

Description

technical field [0001] The invention belongs to the technical field of nonferrous metal alloys, in particular to a method for preparing CuFe alloy materials with different Fe contents by adopting vacuum induction melting. Background technique [0002] As high-strength and high-conductivity copper alloys are widely used in various industries, higher requirements are placed on the performance and manufacturing costs of such high-strength and high-conductivity copper alloys. Copper-iron alloys have the electrical conductivity, thermal conductivity, and ductility of copper at the same time. properties such as resistance, elasticity and iron's wear resistance, strength, hardness, magnetism and other properties, showing unique and superior characteristics, such as electromagnetic wave shielding, elasticity, conductivity, heat release, wear resistance, antibacterial properties etc., and copper-iron alloys can be processed into various physical forms such as rods, cables, plates, fi...

Problems solved by technology

Among them, the mechanical alloying method: grind a certain proportion of Cu powder and Fe powder in a high-energy ball mill for a long time, so that the metal powder will continuously refine its structure during frequent collisions, and finally achieve atomic level mixing to achieve alloying purpose, but this method is easy to substitute impurity elements in the ball milling process, and the cost is high; deformation in-situ composite method: the original structure of CuFe in-situ composite material is generally uniformly distributed on the Cu matrix with dendrites (melting method) or particles Shaped (powder metallurgy method) Fe phase, after a large amount of deformation, the Fe phase becomes fibrous

In order to better improve the comprehensive performance of CuFe alloy, the deformation aging method is often used, and several steps of heat treatment are added in the middle of the deformation, which is still in the research stage; vacuum arc melting method: put a certain proportion of copper and iron blocks into the vacuum induction furnace It is melted inside and poured into the mold after it is completely melted. Usually, the induction melting method and deformation aging are combined to improve the performance of the copper-iron alloy, but this common induction melting method is easy to cause segregation;

[0005] Some of these methods are relatively expensive, and some cannot achieve mass production. The existing vacuum induction smelting method needs to add rare earth elements. The present invention provides a preparation method using vacuum induction smelting for the deficiencies in the prior art.
