Foreword Free

ASM Handbook Volume 4D is the fourth of five volumes to be published on heat treatment. Volume 4A covers the basic fundamentals and processes of steel heat treatment, while Volumes 4B and 4C cover the technological aspects of steel heat treating in terms of basic furnace system and controls (Volume 4B) and induction heating and heat treatment (Volume 4C).

Volume 4D concludes the coverage on ferrous heat treatment with over 40 articles on the heat treatment and properties of the many different types of steels and cast irons. The process of steel selection for direct hardening and surface hardening also is covered in more detail. This gives designers and heat treaters more data and reference information for both component and process design.

We thank the volunteer editors, authors, and reviewers for participating in this enormous effort. The result is a substantive reference work that reflects the continuing commitment of the Heat Treating Society and ASM International in serving technical communities with the tools to solve problems. We are especially indebted to the Volume Editors, Jon Dossett and George E. Totten.
