Effect of initial microstructures on the properties Acicular ferrite steels Properties of steels and their

This study aims to investigate the effect of initial microstructures on the properties of ferritemartensite dual-phase pipeline steels with strain-based design. For this purpose, the as-received acicular ferrite steels were first austenitized at 920 °C for 15 minutes followed by air cooling and water quenching to produce ferrite-pearlite and ferrite-martensite microstructure, respectively.(plate) Acicular ferrite steels Properties of ste(steel) acicular ferrite vs widmanstatten ferriteferrite microstructureacicular martensitecalcium ferriteslist of ferritic steelsmartensitic vs ferriticmartensitic vs austeniticferritic stainless steel gradesSome results are removed in response to a notice of local law requirement.

WhitemanEffect of hot rolling conditions on the microstructure and Acicular ferrite steels Properties of steels and their (steel) Feb 03, 1998On the other hand, it has been shown that the dual phase steels possess the relatively good combination of strength and formability due to their characteristic microstructure. The major microstructural constituents of dual phase steels are soft ferrite and hard martensite/bainite with small amount of retained austenite.

Jul 17, 2019Moreover, the room-temperature tensile properties of the steels were explored at different cooling rates after the rolling process. The results showed that as the cooling rate increased from 0.0094 to 0.13 °C/s, the amount of carbonitride precipitate gradually decreased, such as titanium carbide, leading to the relatively low tensile strength.(plate) Cited by 64Publish Year 2017Author Yi Shao, Chenxi Liu, Zesheng Yan, Huijun Li, Yongchang LiuInoculated acicular ferrite microstructure and mechanical Acicular ferrite steels Properties of steels and their (steel) Rare earth elements and their properties and their applications in steels 1.

Formation mechanism and control methods of acicular Acicular ferrite steels Properties of steels and their

May 01, 2018Acicular ferrite plays an important role in improvement of strength and toughness in HSLA steels. This paper focuses on formation mechanism and control methods of acicular ferrite in HSLA steels. Phase transformation kinetics and formation mechanism of acicular ferrite was reviewed.(plate) Microstructure and properties of ferritic steel welds Acicular ferrite steels Properties of steels and their (steel) Aug 01, 1995The combined effect of Al and Ti, in the range 5 to 500 ppm, on the microstructure and properties of C-Mn shielded metal arc welds has been studied. It was found that Ti, in contrast to Al, dramatically enhanced the formation of acicular ferrite and improved notch toughness.(plate) Microstructure characteristics and mechanical properties Acicular ferrite steels Properties of steels and their (steel) Apr 12, 2012The relation between microstructure characteristics and mechanical properties of X80 pipeline steels was investigated using optical microscopy, scanning electron microscopy, etc. It is shown that the structure consists of polygonal ferrite (PF), quasi-polygonal ferrite (QPF), acicular ferrite (AF), and granular bainitic ferrite (GF).

X70 (steel A) and X80 (steel B) pipeline steels were fabricated by ultra fast cooling (UFC). UFC processing improves not only ultimate tensile strength (UTS), yield strength (YS), yield ratio (YS/UTS), and total elongation of both steels, but also their Charpy absorbed energy ( A K ) as well. The microstructures of both steels were all composed of quasi polygonal, acicular ferrite (AF), and Acicular ferrite steels Properties of steels and their (plate) Nature of inclusions in steel weld metals and their Acicular ferrite steels Properties of steels and their (steel) Jul 19, 2013(1987).

The Influence of Thermomechanical Processing Conditions

AbstractIntroductionExperimental ProcedureExperimental ResultsDiscussionConclusionRolling temperature and rolling reduction intensively influence the formation of Luder lines and fluting marks in mild steels. They govern these effects through control of strain aging. In order to enhance the strain aging resistance and the consequent reduction of yield point elongation and fluting intensity, warm rolling without using the skin pass process is applied. The development of microstructure and crystallographic textures during deformation process and the determination of fluting intensity and mecSee more on hindawiInTech-Chemical and Physical Properties of Fluxes For Saw Acicular ferrite steels Properties of steels and their (steel) 13.
