Anotace knihy

Carburization is a high temperature corrosion phenomenon caused by the unwanted ingress of carbon into alloys used in the process and heat treating industries. It is the most common cause of failure of ethylene cracking tubes and can drastically affect the life of retorts, baskets, conveyors, fans and other components used in heat treating operations. Carburization has a severely adverse effect on ambient temperature ductility and toughness and on weldability. The need for common testing methods for ranking existing alloys and for evaluating new ones has long been recognized. Such tests would allow comparison of the results from different test laboratories and could also be used to compare materials' performance at higher temperatures and different carburizing potentials. Part I of this book is an in-depth review of current state-of-the-art on the carburization phenomenon, the thermodynamics and kinetics of the various reactions that can occur, and the reasons various materials behave as they do. Also covered in detail are the effects on various properties. Part II discusses the variables that are involved in carburization testing and establishes preferred parameters for two testing methods: Discontinuous Gas Carburization and Pack Carburization. Detailed are sample source, size and finish, cleaning, measuring and weighing, temperature and exposure time, gas composition or pack medium, and methods for assessing the degree of carburization.
