Abstract
A system and method for producing locally austempered ductile iron includes a computer program for closely controlling the heating and cooling of an iron part or workpiece. The process allows for the austempering of a relatively low cost iron workpiece to produce significantly higher quality end products. The locally austempered regions may be formed to a substantial controlled depth.
