It is known to disperse reinforcing powders in A1 alloys.
前記強化粉末は、Ａ１合金溶湯中に添加すると溶解する
為、従来、粒子分散強化型合金は焼結法によって製造し
ている。Since the strengthening powder dissolves when added to the molten A1 alloy, particle dispersion strengthened alloys have conventionally been manufactured by a sintering method.

に均一に分散させることが困難であるばかりでなく、製
造コストは高く、又、寸法精度も劣るという問題点があ
る。However, the sintering method has problems in that it is not only difficult to uniformly disperse the A1 alloy powder in the alloy powder, but also that the manufacturing cost is high and the dimensional accuracy is poor.

も高価であり実用上用途が限定されるという問題点があ
る。However, in JP-A No. 63-79934, expensive Ni powder or Ni-based intermetallic compound is used as the reinforcing powder, so although it is cheaper than the sintering method, it is still expensive and has no practical application. The problem is that it is limited.
又、耐摩耗性においても向上はみられるものの、今だ充
