When a large current flows through it and the temperature rises, it becomes soft, so if welding is carried out at this high temperature, the tip of the electrode tip will be severely deformed, resulting in the problem that the strength of the welded part will be insufficient. was.
それゆえに、この発明の目的は、高温になったとしても

優れた製品を得る。Means for Solving the Problems In the method of manufacturing copper-chromium alloy products according to the present invention,
First, rapidly solidified alloy powder having a composition containing at least 0.1 to 1.5% of Or with the remainder being Cu is applied to a conduit formed between a rotationally driven driving wall surface and a fixed fixed wall surface. After that, the alloy powder, which is moved inside the pipe by the frictional force with the driving wall surface, is continuously fed into a rod-shaped or linear body by an extrusion die installed at the end of the pipe. Then, by cold working the rod or linear body, a product with excellent softening resistance is obtained.
「少なくともＣｒを含有Ｊするのは、Ｃｒが耐軟化性に
対して良好な影響をもたら覆からである。``The reason for containing at least Cr is that Cr has a good effect on softening resistance.
Ｃｒ含右伍を１０．１〜１．５％ｊとしたのは、０．１

電性を有するからである。The reason for setting the Cr content to 10.1 to 1.5% is 0.1
%, there is no effect on softening resistance, and 1.
This is because if it exceeds 5%, the effect on softening resistance will be saturated. [The remainder is Cu J because OL+ has good conductivity.
「合金粉末」状に急冷するのは、たとえば棒状（こする
ことに比べて良好な焼入性が得られるからである。The reason for rapidly cooling into the form of "alloy powder" is that better hardenability can be obtained compared to, for example, rubbing it into a bar shape.
合金粉末を、駆動壁面との摩擦力によって移動させ、そ

外部からの圧縮力が加わると、合金粉末は互いに金属接
合される。そしてこの際、Ｃｒかほど良く時効析出され
る。The reason why the alloy powder is moved by the frictional force with the driving wall surface and then continuously extruded as a rod or linear body by an extrusion die is as follows. That is, the alloy powder supplied into the pipe generates heat due to the sliding force between the powders caused by internal plastic flow based on friction within the pipe. In addition to this heat generation, when an external compressive force due to a pushing force is applied to the alloy powder, the alloy powder is metallurgically bonded to each other. At this time, Cr is properly aged and precipitated.
また、押出し後に熱間加工ではなく「冷間加工」するの
は、再結晶による過時効を避けるためである。Furthermore, the reason why "cold working" is performed instead of hot working after extrusion is to avoid overaging due to recrystallization.
合金粉末は、好ましくは、Ｃｒに加えて、Ａｏ。The alloy powder preferably contains Ao in addition to Cr.

℃／ｓｅＣ，以上の速度で冷却されて製造される。Preferably, in order to precipitate supersaturated solid solution Cr, the rod or linear body extruded by an extrusion die is heated at 400 to 600°C in a pre-process, intermediate process, or mock process of cold working. It is left under humidity for 30 minutes to 24 hours. This has a positive effect on thermal and electrical conductivity and softening resistance.
It is manufactured by cooling at a rate of ℃/secC or more.

Therefore, a copper-chromium alloy product having excellent softening resistance and high temperature stability can be obtained. In addition, since it is a copper alloy that has been precipitated by aging, it has a higher 13 electrical conductivity and good thermal conductivity than other materials. Furthermore, it goes without saying that it has higher toughness than ceramics and the like.
