Abstract

Steels with carbide-free bainite containing high carbon austenite at minimal fractions of ferrite and martensite are considered as a real candidate to meet requirements of steels of third generation. The chapter presents the main concept of their processing and the fundamentals of relationship of structure and mechanical properties. Effects of steel composition on kinetics of bainite transformation are discussed as well as factors determining the strength of this group of steels. Conditions ensuring the best combination of strength and formability including high hole expansion values are discussed.
