JPS58217652A - Preparation of copper-oxide type highly conductive material - Google Patents

Abstract

PURPOSE:To easily prepare a highly conductive material excellent in softening resistance, by a method wherein the fibrous peaces of a copper alloy containing an easily oxidizable metal are subjected to heat treatment in an oxidative atmosphere and, after crushing, the crushed alloy is pressed to be sintered. CONSTITUTION:The cast ingot of a Cu alloy containing one kind or more easily oxidizable alloying element such as Al, Si, Ti, Mg or Be is subjected to solid heat-treatment to uniformize the composition thereof. After this Cu complex alloy ingot is shaved into fibrous pieces, they are heated in an oxidative atmosphere to subject the part or all of the alloying element to internal oxidation. This oxidized pieces are finely divided by a ball mill and the resulting powdery alloy is subjected to press molding to form a molded alloy which is in turn sintered at a high temp. and repeatedly subjected to processing such as extrusion, rolling or wire drawing and annealing to prepare a Cu-oxide type highly conductive material as a wire material. By this method, a conductive material excellent in tensile strength, conductivity and softening resistant characteristics can be easily prepared.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a steel-saponified 445I material with metal particles dispersed in the southern matrix,
This is a unique and inexpensive version of the l1iiJ44 model, which was recently expanded.

Generally, a sea bream with metal oxides dispersed in a steel matrix.
The oxidized thread material has a low resistance, and has excellent strength and softening resistance in one field, so it can be used as a material that is resistant to heat. I'm in two phases.

This kind of shoulder-oxidation gj system Shangdao (what school of Eikyiwanden is that the first Matsumoto nl kundai to be sintered with the wood metallurgy method of powder sintering, and the A1.8 Heavy, 'r phoenix.g, B
An internal oxidation method is known in which an alloying element system that is easily oxidized, such as E, is treated in a droplet atmosphere to internally ferment the alloying element system.

However, in the case of Matsumoto Yoshiyuki, acclimatization@nucleons become coarser,
There are mermaids that are difficult to disperse on the moon, and the internal oxidation method takes a long time to oxidize the circular parts of large materials such as people and thick plates.
There was a mermaid who was unable to make the chemical particle forgive q - for a long time.

In order to solve this problem, the present invention, as a result of extensive studies, has developed a monomonooxide primary 11i6#4 material, which has been made uniform in the dispersion of particles and improved in C+td softening properties, in a simple and inexpensive manner. In order to open up a manufacturing method that can be preserved, alloy elements that are easily converted are cut into l#i fibrous pieces, which are then heated in air for acclimatization. After processing to internally oxidize some or all of the alloying elements, it is pulverized into powder, which is then compacted and sintered.

That is, one aspect of the present invention is that Cut=AI, 8i, T1. rvi
g, Be4 - cut the joints that are easily oxidized by one or two or more lengths - cut the joints and cut the fibers in the shape shown in (B), ←9. The cut pieces are then blackened in an acid atmosphere to internally oxidize some or all of the elements.This is then transformed into a powder.

The powder is sintered and made into a 11-sensed yarn 4@ material, which is then exported as needed, rolled, processed at Shintsuki-dera, and sintered repeatedly to form an 81T wax shape and T. It is something that

Either a lump or a processed material can be used as the Ichigo Akon, but depending on the Goso thread, a lump may be processed to make the alloy composition into an M-form, or it may be processed by rolling, heat treatment, etc. #M
It is embarrassing to use something that has been processed and detained. In addition, the reason why the fibrous pieces were made by cutting the southern lumps was to make the same group oxidation treatment into each part and to carry out the subsequent crushing t-1.In particular, the reason why the fibrous pieces were made by cutting was , and other processed poems.

For example, this is because it is the cheapest method compared to rolling, elongation, etc., and it is easier to form a dla-shaped piece. However, in order to uniformly process the fibrous particles in a short time, it is desirable to set the maximum diameter of the fibrous pieces to 1.01 F or more, and also to reduce the size of the fibers and separated pieces. It facilitates grinding, grinding, etc. after internal fermentation treatment, and improves the flatness of powder and excellent
In order to improve the customization of the material, it is preferable to set the ratio lA) of the maximum diameter of the fibrous piece to the length l to 10~500.

Forward, cutting 4! As for the method of holding the paddle-shaped piece, it is not yet fixed, but using a steel joint 4 or a ridge, knurling the 7-piece cloth 4 to form an uneven shape, and making this I! Either J split machining or cutting edge 4 or temporarily can be done by machining the cut Uυ machining T while using the cutting blade Roe 0 tool with following movement.Also, - acclimation treatment of #A3 part of the one-piece piece. For example, it is sufficient to perform a zero-black filter treatment in a mixed gas of liquid gas and brewing gas.

Is this the invention of F1? I will explain actual examples to the prayer.

A portion of the Cu-1,0% A1 compound was removed by a POW's request for melting.

After soaking the superior 5JJA at 900 degrees Celsius in an argon stream for 8 hours, it was cooled in water to equalize the alloy composition, and then cut using a lathe and a cutting tool. 11th (a), 轡, i/i, obtained a di fibrous piece with a small T shape and the size shown in Table 1.

This was carried out at 80% in argon gas with 0.1%
Heat the skin at 0°C for 5 hours to release the AI in the inner layer.
L let me go. This is then ball milled to reduce the flat diameter to FJ2μ.
Grind it into a fine powder and press it with 300Mp from a kt output specific pressure press.
After pressing it with a pressure of 100%, it was tied at a temperature of 850°C and a 10.1M diameter tube was ejected. Adding striped wire drawing to this, Roe and sintered wire were added to create a steel wire with a diameter of 15 mm.
The 4 materials were passed through the material. For these 44 materials, the 44 degrees, 44 degrees, and the degree of semi-softening were determined. The dried rice is also listed on the first page of the condolence sheet.

For comparison, 1.0% A1 was added to steel powder (AJ
.

()s) This was mixed as a powder, and this was also listed in Table T41 of the properties of 44N material, which was produced by the conventional Matsumoto Yasho method and processed 3 times in the same manner as the binder.

In addition, for semi-softened m degree in Table 1, add 4 to 30 minutes to 11 (
/J Kaguro treatment showed the strength of the average strength of processed material and dull material in mlf.

s 1 As is clear from Table 1, the process of the present invention improves the workability of Mi material compared to the conventional method,
It can be seen that the strength and semi-softening of the #14@ material were properly crushed. Special 52+A, maximum diameter of d-shaped chamber Dk1.0
The ratio of maximum diameter to length 1 is 1/1) from lO to 5.
00 has good workability with flattening 4N, and road/f
It can be seen that the semi-softening m< is still sufficient.

Same, maximum 141) and the ratio of length l! Those with a diameter of 500 mm or more had poor linkage during cutting and acclimatization, and were not practical.

In this way, according to the d24 invention, 5! 1ilJt and the failed 11-kikkakan Ito Sho Sen Ichimoku fee of the 5!
It is something that has d4-fΦ in the song, and it has an industrially advanced effect 7a-.

4.1 The rapid glare of the surrounding area (condolences), I (2), and the V field greatly increase the unbuttoned light force, - the representative side of the male-shaped cutting piece is carefully examined. Melt.
