Book excerpt: Annotation Based on his training in metallurgy and experience in a large British gear manufacturing company, Parrish reviews the microstructural features of metal products that have been carbon case-hardened, and the influence of those features on the more important material properties. He is not concerned with the carbonizing process at all. He primarily addresses students of engineering and ferrous metallurgy, but also stress and design engineers who might want to understand more fully the specifications of the materials they are considering for their designs. He wrote the eight articles to summarize the field's literature of the early 1970s for his own convenience, but at invitation, published them as a series in the Heat Treatment of Metals during 1967-77, and collected them for a first edition of the volume in 1980.
