Compared with the copper alloy with high strength and high conductivity of other systems, the fusing point of alloying element Fe is relatively low in Cu-Fe system, is easier to
Melting, and non-miscible gap of Fe and Cu is small, the deformability of alloy is preferable, and machinability is preferable, so closing about Cu-Fe system
The research of gold receives attention, becomes one of the important directions of copper alloy with high strength and high conductivity development.
Currently, high-strength highly-conductive Cu-Fe system alloy mainly utilizes fusion casting to prepare just alloy, then first alloy is carried out subsequent
The processing such as heat treatment, deformation, obtain the Cu-Fe system alloy of final use state.When founding prepares just alloy, due to solidification
Cooling velocity is very fast, it is easy to cause to be dissolved a large amount of Fe element in Cu matrix, the serious electric conductivity for reducing Cu-Fe alloy.Though
So oversaturated Fe is constantly precipitated during subsequent heat treatment, thermomechanical treatment etc., but under low temperature Fe diffusion velocity it is very slow,
It is difficult the Fe that will be dissolved in Cu to be precipitated completely, and solid solution of the Fe in Cu is to reduce the main influence factor of Cu-Fe alloy.Institute
With the electric conductivity in order to improve Cu-Fe alloy, need to reduce solid solution capacity of the Fe in Cu.
In the prior art frequently with the methods of deformation, heat treatment, high-intensity magnetic field, multi-element alloyed, but cannot all solve well
Certainly this problem.Such as: Ag is considered as that damage Cu alloy conductive acts on the smallest element, but utilizes Ag to Cu-Fe alloy
The Cu-Fe-Ag alloy of alloying preparation is carried out, but is still dissolved 2.5% or more Fe in its as cast condition Cu matrix；And Ag also drops
The low stability of Fe phase fiber, causes Fe phase to be roughened at 350 DEG C or more, and reduction limits the use temperature range of alloy；And
And use Ag alloying higher cost.The Fe being dissolved in Cu can not be equally reduced to very low state by other methods.
In order to more effectively reduce the Fe being dissolved in Cu, it is necessary to provide a kind of Cu-Fe-C-Ag alloy.
Summary of the invention
The purpose of the present invention is to provide a kind of Cu-Fe-C-Ag alloys, can efficiently reduce the Fe being dissolved in Cu-, mention
The high electric conductivity of Cu-Fe alloy, also improves the stability of Fe phase fiber, Fe phase will not be caused to be roughened at 350 DEG C or more,
The use temperature range of alloy is improved, and reduces the preparation cost of alloy.
To achieve the goals above, the invention provides the following technical scheme:
A kind of Cu-Fe-C-Ag alloy, Cu-Fe-C-Ag alloy are prepared by the following steps:
(1) prepare raw material: raw material includes Cu-Ag prealloy powder and Fe-C prealloy powder,
(2) ball milling mixing: being added abrading-ball and carry out powder mixing machine, obtain composite powder,
(3) hot pressed sintering: composite powder obtained in step (2) being put into hot-pressed sintering furnace and is sintered, sintering temperature

43min, 44min),
Obtain the Cu-Fe-C-Ag alloy of Fe-C even particle distribution.
It is a kind of novel high-strength highly-conductive Cu alloy by Cu-Fe-C-Ag alloy prepared by above-mentioned steps, C and Cu is utilized
Mutually exclusive effect in Fe-Cu-C ternary system, therefore C is added, and into Cu in order to give full play to this work of C
With using Cu-Ag prealloy powder, Fe-C prealloy powder hot pressed sintering preparation Cu-Fe-C-Ag alloy.Cu-Fe-C-Ag obtained
It is 54%~66%IACS that the tensile strength of alloy, which is greater than 570MPa, conductivity,.
In alloy of the invention, the partial size of Cu-Ag prealloy powder is 10~50 μm as a preferred implementation manner,.
When the partial size of Cu-Ag prealloy powder is 10~50 μm, Fe-C particle can be more evenly distributed in Cu-Ag matrix.Fe-C is closed in advance
