Heat resistant slide member for internal combustion engine

摘要

A heat resistant slide member for an internal combustion engine is a plastically worked member formed from a quenched and solidified aluminum alloy, with a metal flow line in a sliding portion thereof set in a sliding direction. The aluminum alloy contains at least one selected from the group consisting of Cr, Fe, Zr and Ti in an amount of 5% or more and 30% by weight or less and has an average diameter of precipitates and crystallizates therein of 50 mu m or less and a tensile strength at 300 DEG C. of 18 kg/mm2 or more.
