A Model for the Microstructure of Some Advanced Bainitic Steels
Some applications of phase transformation theory towards the exploitation of bainitic microstructures are discussed , with particular emphasis on the quantitative aspects of alloying element effects. Examples are used to illustrate the principles involved in the design of advanced bainitic alloys of the type currently under investigation in the steel industry.
متن کاملThe Microstructure of Continuously Cooled Tough Bainitic Steels
The influence of bainite morphology on the impact toughness behaviour of a continuously cooled cementite free low carbon C-Mn-B type of steel has been examined. Different bainite morphologies were obtained by cooling from the austenite regime to ambient temperature with different cooling rates. The resulting microstructures have been quantitatively analysed using light optical microscopy (LOM),...
متن کاملAir cooled bainitic steels for strong, seamless pipes Part 1 – alloy design, kinetics and microstructure
Seamless pipes are usually quenched and tempered after manufacture in order to obtain the desired properties. The possibility of avoiding this heat treatment is explored here, by designing steels which transform into an carbide free bainitic microstructure during cooling from the hot processing phase of the pipe. The cooling conditions studied are appropriate for the manufacturing process and c...
متن کاملAir cooled bainitic steels for strong, seamless pipes Part 2 – properties and microstructure of rolled material
In the first part of the present study, two steels were designed with the aim of achieving properties consistent with the specifications for the manufacture of seamless pipes. The alloys were intended to develop into mixtures of bainitic ferrite and carbon enriched retained austenite during cooling to ambient temperature from the pipe forming operations, thus avoiding the need for subsequent he...
متن کاملA Constitutive Relationship between Fatigue Limit and Microstructure in Nanostructured Bainitic Steels
The recently developed nanobainitic steels show high strength as well as high ductility. Although this combination seems to be promising for fatigue design, fatigue properties of nanostructured bainitic steels are often surprisingly low. To improve the fatigue behavior, an understanding of the correlation between the nanobainitic microstructure and the fatigue limit is fundamental. Therefore, o...
