Abstract
A cylinder liner for high temperature, high performance engine applications is cast from gray iron material and thereafter austempered for a time sufficient to achieve a substantially bainitic microstructure that is stable against excessive thermal growth when the liner is exposed to extreme operating temperatures of about 450° F. for an extended period of time of about 20 hours.
