دانلود کتاب Quenching and Carburising - Proceedings of the Third International Seminar of the International Federation for Heat Treatment and Surface Engineering

Quenching and carburising are two of the most basic and widely practiced steel heat treatment processes. Each allows the base properties and performance of the steel to be significantly enhanced, such that a relatively inexpensive and simple starting material can be used for a wide range of demanding applications. Nevertheless, the technological developments within those two processes are often ignored in favor of 'high tech' surface treatments. This book includes the proceedings of the Third International Seminar of the IFHT, 1991. The sessions devoted to quenching cover a range of topics from the measurement of quench intensity, through to applications within the heat treatment and steel processing industries.
