Embodiment 1

[0007] Take the required chemical components, Cu is 14wt%, Mg is 11wt%, Mn is 1.3wt%, Cr is 3wt%, Ir is 0.13wt%, Al is 34wt%, and the balance is Fe. Put all the ingredients into the smelting furnace, keep the vacuum, carry out smelting, heat the temperature to 1150°C, heat it and roll it into an alloy plate, then slowly lower the temperature to room temperature, the cooling rate is 40°C / s, and prepare copper and aluminum Iron alloy material.

Embodiment 2

[0009] The preparation method is the same as in Example 1, and the composition ratio of each component is: Cu is 12wt%, Mg is 5wt%, Mn is 0.7wt%, Cr is 3.5wt%, Ir is 0.17wt%, Al is 45wt%, and the balance is Fe .

Embodiment 3

[0011] The preparation method is the same as in Example 1, and the composition ratio of each component is: Cu is 13wt%, Mg is 8wt%, Mn is 1.0wt%, Cr is 4wt%, Ir is 0.22wt%, Al is 56wt%, and the balance is Fe.

[0012] The products of Example 1, Example 2, and Example 3 were tested for impact toughness. The test standard is GB / T1817-1995, and the impact toughness values ​​of the products of Example 1, Example 2, and Example 3 are 630J, 645J, and 660J respectively, which have good impact toughness.

Abstract

The invention relates to a Cu-Al-Fe alloy material. The Cu-Al-Fe alloy material comprises the following components in weight percentage: 12-14 wt% of Cu, 5-11 wt% of Mg, 0.7-1.3 wt% of Mn, 3-4 wt% of Cr, 0.13-0.22 wt% of Ir, 34-56 wt% of Al, and Fe in balancing amount. The prepared alloy of copper, aluminum and iron has very high impact tenacity.

Description

technical field [0001] The invention relates to an alloy material, in particular to a copper-aluminum-iron alloy material. Background technique [0002] When the alloy material is subjected to external impact, the toughness and impact resistance of the alloy material are very critical. If the toughness is poor and the impact resistance is small, it will have a destructive effect on the texture of the alloy material. At this time, if the alloy material has very high impact toughness, the above hazards can be avoided. At present, improving the impact toughness of alloy materials is a research hotspot in related fields. How to greatly improve the impact toughness of alloy materials is a difficult point that plagues technicians in related fields. Contents of the invention [0003] The technical problem to be solved: the problem of low impact toughness of ordinary alloy materials. [0004] Technical solution: The invention discloses a copper-aluminum-iron alloy material, whic...
