Morphology and growth process of bainitic ferrite in steels

Metals and Materials, 1998
The morphologies and the formation mechanisms of isothermally transformed Widmanstatten ferrite and bainite in various steels were investigated. Widmanstatten ferrite often grew from the grain boundary ferrite allotriomorph formed by a diffusional mechanism in the temperature range of the upper C-curve, whereas, bainite grew directly from an austenite ...

Changes in the fracture strength parameters of ferritic–bainitic and bainitic pipe steels during operation

Russian Metallurgy (Metally), 2016
The fracture strength and the sensitivity to delayed fracture of the pipes in oil-trunk pipelines that are made of ferritic–bainitic and bainitic steels are studied. The results of modeling of the delayed brittle fracture of pipe steel during a simultaneous action of mechanical stresses and a corrosive medium are presented.

Do bainitic and Widmanstätten ferrite grow with different mechanisms?

Scripta Materialia, 2010
Caballero et al. recently presented new evidence for different growth mechanisms of Widmanstatten and bainitic ferrite. Their argument was based on Zener's hypothesis of diffusionless growth of bainitic ferrite. It is now demonstrated that Bhadeshia's model, based on Zener's hypothesis, predicts that some of the new measurements, claimed to fall above ...

Impact properties of tempered bainite–ferrite dual phase steels

Materials Science and Engineering: A, 2010
Abstract To improve both strength and toughness of AISI 4340 steel three microstructures, full bainite, bainite–ferrite and tempered bainite–ferrite, were produced by heat treatment of this steel. Tensile, impact and hardness properties of these microstructures were compared.

Fracture properties of ferritic, ferritic- pearlitic, pearlitic and bainitic nodular cast irons

1986
The use of nodular cast irons in components having high safety requirements has increased rapidly during last years. Casting permits a design where the stress concentrations are minimised and the cast material itself has shown to have good mechanical properties which can be obtained repeatedly. Although the conventional mechanical properties of nodular

Modeling the austenite decomposition into ferrite and bainite

2005
Novel advanced high-strength steels such as dual-phase (DP) and transformation induced plasticity (TRIP) steels, are considered as promising materials for new generation of lightweight vehicles. The superior mechanical properties of these steels, compared to classical high strength steels, are associated with their complex micro structures. The desired
