Alloyed Gray Cast Iron for Machine Components

Abstract

Quality of a material means nothing in itself because quality is closely related to the service affecting proper lies of the particular material in a particular application. Having in mind the particular applications of gray cast iron for machine components, the advantages of alloying and the general effects of the alloying elements nickel, copper, chromium, molybdenum and vanadium are discussed on a theoretical basis as well as from the point of view of praClical experience. The combined effects of graphitizing and carbidestabilizing alloying elements is also considered, but the most careful atten tion is given (0 the correlation between struCll!re (depending upon composition and cooling ralc) and service properties (depcnding upon the application considered), Actnal practice ;lnd recent developments in the field of alloyed gray irons for diesel engine and machine tool components are reviewed and diSCLIssed.
