Some Service Failures arising from Various Types of Corrosion

Abstract

The Research Laboratory of the Development and Research Department of The Mond Nickel Company Limited, has been concerned is developing new heat and corrosion-resistant alloys to meet the demands of designers of gas-turbine chemical plant and electrical equipment.Premature service failures in these materials are not common, and when they do occur they can usually be traced to misuse or mal-treatment of the material during fabrication or appli-cation, or to some form of accidental contamination or damage. Important lessons have nevertheless been learned from post-mortem examinations of service failures, and the following five examples have been selected as of interest not only to works' metallurgists but also to designers, to whom these special materials offer new possibilities, and to fabricators, to whom they present certain problems.
