本発明は分散強化合金鋳物の製造方法に関し、
特にアルミニウム合金等の金属に強化用微粒子を
分散させることにより、強度等を向上させること
ができる分散強化合金鋳物の製造方法に関する。[Detailed Description of the Invention] [Technical Field] The present invention relates to a method for manufacturing dispersion-strengthened alloy castings,
In particular, the present invention relates to a method for producing dispersion-strengthened alloy castings that can improve strength etc. by dispersing reinforcing fine particles in a metal such as an aluminum alloy.

Dispersion-strengthened alloys in which hard, fine particles that are stable even at high temperatures are dispersed and composited in a metal matrix are known. For example, for aluminum and matrix, SAP (Sintered Aluminum
Powder) is well known. Fine particles dispersed in this metal matrix prevent metal transfer and improve strength. Therefore, the greater the amount of fine particles present in the metal matrix and the more uniformly they are dispersed, the higher the strength will be.
ところで、かかる分散強化合金鋳物を製造する
ためには、溶湯と強化用微粒子を混入させる工程
が必要となる。この溶湯中に強化用微粒子を混入
させる時期の違いにより、従来は次の２つの製造
方法が行われている。 By the way, in order to manufacture such dispersion-strengthened alloy castings, a step of mixing molten metal and reinforcing fine particles is required. Conventionally, the following two manufacturing methods have been used, depending on the timing at which reinforcing fine particles are mixed into the molten metal.
第１の従来法は、炉の中で溶湯と強化用微粒子
を撹拌混合し、（例：ボルテツクス法）、それを金
型に重量鋳造で鋳込むものである。 The first conventional method involves stirring and mixing molten metal and reinforcing fine particles in a furnace (eg, vortex method), and then casting the mixture into a mold by weight casting.
この第１の従来法においては、一般にセラミツ

凝固時間が長いこと等により、強化用微粒子の分
離傾向は増々大きくなり、従つて、均一な分散が
確保できないという問題がある。また、炉内の撹
拌装置が必要となり、スペースをとるとともに、
コスト高になるという問題がある。 In this first conventional method, the reinforcing particles generally separate and float when stirring in the furnace is stopped due to poor wettability with the molten metal and differences in specific gravity of the reinforcing particles made of ceramic or the like. In addition, due to the time it takes to cast from the furnace into the mold, and the long solidification time of the molten metal in the gravity casting method, the tendency for the reinforcing fine particles to separate becomes even greater. There is a problem that uniform dispersion cannot be ensured. In addition, a stirring device inside the furnace is required, which takes up space and
There is a problem of high cost.
この対策として、強化用微粒子と溶湯の濡れ性
を改善することが考えられ、強化用微粒子の表面
に濡れ性改善用のコーテイング層を設けたり、溶
湯に濡れ性を改善する成分を添加する等の方法が
採られているが、必ずしも十分なものではなく、
かつコスト高の要因となつている。 As a countermeasure to this problem, it is possible to improve the wettability between the reinforcing fine particles and the molten metal, such as providing a coating layer to improve wettability on the surface of the reinforcing fine particles, or adding a component that improves wettability to the molten metal. Although methods have been adopted, they are not necessarily sufficient.
This is also a factor in high costs.
第２の従来法は、金型に溶湯を鋳込む経路の途
中で強化用微粒子を混入させるものである。この
方法には、溶湯に渦巻流を起こさせることにより
混入する渦巻鋳造法、溶湯流中に高速で強化用微
粒子を混入させる噴射分散法等がある。 The second conventional method is to mix reinforcing fine particles in the middle of the path of casting the molten metal into the mold. This method includes a spiral casting method in which reinforcing fine particles are mixed into the molten metal by creating a swirl flow, and an injection dispersion method in which reinforcing fine particles are mixed into the molten metal flow at high speed.
しかしながら、第２の従来方法では、金型に流
れ込む流体に強化用微粒子を混入させるものであ
るため、量的に限界があり、かつ分散量が少ない
という問題がある。また、一般に重力鋳造による
ため凝固時間が長く、強化用微粒子が凝縮する等
して均一な分散状態が得られないという問題があ
る。 However, in the second conventional method, since reinforcing fine particles are mixed into the fluid flowing into the mold, there is a problem that there is a limit in quantity and the amount of dispersion is small. Furthermore, since gravity casting is generally used, solidification time is long, and reinforcing fine particles condense, making it impossible to obtain a uniformly dispersed state.
本発明は、上記従来技術の問題を解決するため
になされたもので、強化用微粒子を金属マトリツ

The present invention has been made in order to solve the problems of the prior art described above, and an object of the present invention is to provide a method for producing a dispersion-strengthened alloy casting in which reinforcing fine particles can be uniformly dispersed in a metal matrix.
