が必要とされる。[Prior Art] Recently, engines have been manufactured using aluminum alloys instead of conventional steel materials in order to reduce weight and save energy. However, especially valve lifters, valve spring retainers, oil pump gears, sprockets, and other engine parts require high-temperature strength, wear resistance, and impact properties.

2.One or more kinds of hard particles such as SiO2 are mixed with 0.
It is a heat-resistant and wear-resistant aluminum alloy made by dispersing 5 to 8% of aluminum.
上記において合金成分、硬質粒子の限定理由は下記のと
おりである。The reasons for limiting the alloy components and hard particles in the above are as follows.
Ｃｕ：常温及び高温強度を向上する。２．０％未満では
その効果が小さく、６．０％を超えると効果が飽和する
とともに耐食性が低下する。Cu: Improves strength at room temperature and high temperature. If it is less than 2.0%, the effect will be small, and if it exceeds 6.0%, the effect will be saturated and the corrosion resistance will decrease.
Ｍｇ：Ｃｕと共存して時効硬化して常温及び高温強度を
高める。０．８％未満では効果が十分でなく、３．０％
を越えると効果が飽和する。Mg: Coexists with Cu and ages hardens to increase strength at room temperature and high temperature. If it is less than 0.8%, the effect is not sufficient, and 3.0%
The effect becomes saturated when it exceeds.
Ｓｉ ：Ｓｉの添加によりＡｌ−Ｃｕ−Ｍｇ系析出中間
相（Ｓ″）が微細に形成され、時効硬化量が大きくなる
。更に後述のＭｎが共存していると、Ａｌ−Ｍｎ−８Ｌ
系析出相が生じ、これが転位のピンニング効果を高め、
サブグレイン組織ないし微細な再結晶組織となる。Si: By adding Si, a fine Al-Cu-Mg precipitated intermediate phase (S'') is formed, increasing the amount of age hardening.Furthermore, when Mn, which will be described later, coexists, Al-Mn-8L
A system precipitated phase is generated, which enhances the pinning effect of dislocations,
It becomes a subgrain structure or a fine recrystallized structure.
０．２％未満ではその効果が小さく、１．２％を越える
と効果が飽和するとともにＳｉ晶出物が生じて延性を低
下させる。If it is less than 0.2%, the effect will be small, and if it exceeds 1.2%, the effect will be saturated and Si crystallized products will be produced, reducing ductility.
Ｍｎ、Ｆｅ５Ｎｉ：高温強度の向上に役立つ。Mn, Fe5Ni: Helps improve high temperature strength.
合計量が０．４％未満ではその効果が小さく、４．０％
を越えると粗大な晶出物を生じやすく延性を低下させる
。If the total amount is less than 0.4%, the effect is small, 4.0%
If it exceeds this amount, coarse crystallized substances tend to form, reducing ductility.
Ｔｉ、Ｚｒ：凝固時の結晶粒を微細化するとともに、溶
体化処理中に発生する再結晶を抑制し、繊維状組織ある
いは微細な再結晶を有する組織をつくり、強度を向上さ
せる。合計量が０．０２％未満ではその効果が小さく、
０．７％を越えると効果が飽和する。Ti, Zr: Refine crystal grains during solidification, suppress recrystallization that occurs during solution treatment, create a fibrous structure or a structure with fine recrystallization, and improve strength. If the total amount is less than 0.02%, the effect will be small;
If it exceeds 0.7%, the effect will be saturated.
硬質粒子：５ｉＣＳＳｉ３Ｎ４、Ａｌ２Ｏ３、ＴｉＮ、
ＴｉＣ、ＺｒＯ２−ＳｉＯ２（ジルコン）の如き硬質粒
子を添加することによって耐摩耗性が大幅に向上する。Hard particles: 5iCSSi3N4, Al2O3, TiN,
Wear resistance is greatly improved by adding hard particles such as TiC, ZrO2-SiO2 (zircon).
平均粒径が１μ−未満では十分な耐摩耗性を得られない
。If the average particle size is less than 1 μm, sufficient wear resistance cannot be obtained.
更に粒子の均一分散が困難となり、粒子が偏在する場合
には延性が低下する。平均粒径が８μｌを越すと摩擦す
る相手側の材料を傷つける。相手材が鋳鋼材である場合
には、傷も小さく問題となることはあまりないが、相手
材がアルミ合金のような軟質材である場合には、大きな
摩擦傷が生じる。又、添加量が０．５％未満では耐摩耗
性が十分でなく、添加量が８％を越えると延性と切削性
が低下する。Furthermore, it becomes difficult to uniformly disperse the particles, and when the particles are unevenly distributed, the ductility decreases. If the average particle size exceeds 8 μl, it will damage the material on the other side that is being rubbed. If the mating material is cast steel, the scratches will be small and will not cause much of a problem, but if the mating material is a soft material such as an aluminum alloy, large friction scratches will occur. Furthermore, if the amount added is less than 0.5%, wear resistance will not be sufficient, and if the amount added exceeds 8%, ductility and machinability will decrease.

A vacuum degassing treatment was performed at 80° C. for 1 hour, and this was made into a billet for extrusion. This was extruded at 400°C to a diameter of 1811 (extrusion ratio 15). Then, T6 treatment (480℃
The specimens were subjected to a tensile test and a bottle-disk abrasion test. The results are also listed in Table 1. Here, the wear amount refers to the wear test (120

No. 7 shows sufficiently high strength and elongation at room temperature and 150°C, and furthermore, the amount of wear on the bottle and the disk is small. On the other hand, comparative alloys No. 18-22 have insufficient elongation due to the inappropriate size or amount of hard particles, or the amount of pin wear or disk wear is large, and comparative alloy No. 28-2B has low strength or elongation due to inappropriate aluminum alloy matrix components.

This value is sufficiently high, and it is judged that the alloy of the present invention can be easily cold-forged.
