Some fundamental steps in thermomechanical processing of steels.

AN INVESTIGATION TO BAINITE FORMATION MORPHOLOGIES IN NI-CR BEARING LOW CARBON STEELS THROUGH THERMOMECHANICAL PROCESSING

The presence of bainite in the microstructure of steels to obtain a proper combination of strength and toughness has always been desired. The previous works however have shown that the presence of preferred bainite morphologies in the microstructure of any steel would not be readily accessible. In addition, the appearance of different bainite morphologies in the microstructure of any steel is d...

Fundamental Principles of Heat - Treating Steels

eat-treating is a process that is critical to the fabrication of steel fasteners. It is a necessary process in order to achieve the mechanical properties. Heat-treating is typically conduc t ed a f t e r t he fo rming processes and before any coating or finishing processes. Heat-treating may be done by the manufacturer or outsourced to a commercial shop. The equipment necessary to effect ively ...

Some phase transformations in steels

About 70% of all the steel compositions that are currently used have been developed within the last 10 years. Novel iron alloys are being conceived, manufactured, and marketed with a regularity which has confounded many prophecies. Phase transformation theory has contributed to the successful development of steels. This overview will begin therefore with a discussion of the atomic mechanism by ...

Effect of Thermomechanical Processing on the Microstructure and Mechanical Properties of a Duplex Stainless Steel

Duplex stainless steels (DSSS) have a microstructure composed of ferrite and austenite phases that gives them a very good combination of mechanical and corrosion properties. These steels are desirable for many applications in the chemical and petrochemical industries. In the present study, a type of stainless steel was cast, solution annealed at 1200°C for 60 min and then quenched in water. Ini...
