Determination of Metallurgical and Corrosion Factors Resulting in (1) Localized Graphitization Attack on Cast Iron and (2) Brittle Fracture of Mild Steel Distribution Pipe. Part I

摘要

The objective of the program's basic studies is to determine the metallurgical and mechanics relationships leading to the brittle fracture of mild steel, gas distribution piping, and to develop an understanding of the basic metallurgical characteristics, mechanical (stress) effects and environmental conditions leading to highly localized graphitization attack in centrifugally cast, cast iron. This report will cover the basic objectives, background and brittle fracture of mild steel.
