Abstract

PURPOSE: To contrive the improvement of fatigue strength and hardness of the Al-Sn bearing alloy and the maintenance of high temperature-hardness of the alloy, by adding a metal element having a specific solid solution limit to Al and a specific decomposition temperature of an intermetallic compound with Al to the alloy.
CONSTITUTION: An element having the maximum solid solution limit of a Al side- solid solution of 0.3atom% or more and having a decomposition temperature of an intermetallic compound with Al of the melting point of Al or higher is added to an Al alloy containing 30wt% or less Sn or Sn. As such a metal, Li, Ca, Cr, etc. are mentioned. The addition amount of the metal is determined considering the solid solution limit of it to Al and so that the appropriate deposition amount of its intermetallic compound with Al can be obtained by a heat treatment, but the addition amount need be more than the solid solution limit of it at a normal temperature. The metal element is completely solid solubilized in Al when the alloy is molten, and with the state maintained, the alloy is rapidly cooled. The above-mentioned pulverized intermetallic compound is deposited uniformly in the grain interface of Al by a heat treatment after the rapid cooling. The deposit is not resolubilized into Al and prevents the movement of the Al grain boundaries and also the coarsening of Sn grains.
