Controlled Atmospheres for Heat Treatment

Controlled Atmospheres for Heat Treatment describes the reaction complexities in heat treatment of metals under controlled atmosphere. Organized into 13 chapters, this book begins with the methods and classifications of heat treatment in controlled atmospheres. This topic is followed by the most popular atmospheres of heat treatment, namely, nitrogen and vacuum. The subsequent chapters deal with the components of heat treatment atmospheres, such as exogas, nitrogen base of monogas, endogas, and ammonia. The discussion then shifts to special gas atmospheres, including steam and those produced by cracking organic liquids. This book also covers several heat treatment processes, such as annealing, hardening, tempering, and heat treatment of powder metallurgical products in controlled atmospheres. A chapter describes the common methods used in protective gas techniques. The concluding chapter presents some dangers associated with controlled atmospheres and their corresponding technical safety precautions.
