National Technical Reports Library

The National Technical Information Service acquires, indexes, abstracts, and archives the largest collection of U.S. government-sponsored technical reports in existence. The NTRL offers online, free and open access to these authenticated government technical reports. Technical reports and documents in its repository may be available online for free either from the issuing federal agency, the U.S. Government Publishing Office’s Federal Digital System website, or through search engines.

Production and Machining of Thin Wall Gray and Ductile Cast Iron.

DE2001769201

Publication Date	2000
Personal Author	Li, H.; Griffin, R.; Bates, C. E.; Eleftheriou, E.
Page Count	74
Abstract	The University of Alabama at Birmingham, in cooperation with the American Foundry Society, companies across North America, with support from the US Department of Energy, is conducting a project to develop an understanding of the factors that control the machinability of cast gray and ductile iron. Differences of as much as 500% have been found in machinability have been observed at the same strength. The most machinable irons were those with a high cell counts and few carbonitride inclusions. Additions of tin and copper can be added to both gray and ductile iron to stabilize the pearlite, but excessive additions (above those required to produce the desired pearlite content) degrade the machinability.
