CONTROLLING THE HARDENABILITY OF SINTERED STEELS

Abstract

The factors influencing the hardenability of sintered steels are discussed. Special problems are encountered in establishing hardenability tests suitable for porous materials. A dilatometric method is described by which the transformation characteristics of sintered steel may be determined. Such data can be used directly as a hardenability criterion. Data are given in the form of continuous cooling diagrams on some typical sintered steels.
