A method of producing a fine TiC particle-dispersing type AlSn based
aluminum
alloy includes the steps of: preparing either Al mother-alloy or metallic raw materials
of the Al alloy and a green compact, in which TiC is dispersed; melting the Al
mother-alloy or the metallic raw materials of the Al alloy to form an Al alloy
melt; bringing the Al alloy melt and the green compact, in which TiC is dispersed,
into contact with one another, thereby dispersing the TiC in the Al-alloy melt;
casting the Al alloy melt, in which TiC is dispersed, into an aluminum-alloy ingot,
in which TiC is dispersed; and rolling the aluminum-alloy ingot.
