Macro and microstructural characterisation of high Si cast steels–Study of microsegregation patterns
(Maney Publishing, 2016-11-23)
In this study the as-cast macro and microstructures of medium C – high Si cast steels of three different levels of alloying are characterised. The application of a colour-etching reagent sensitive to Si segregation effectively ...
Study of austempering kinetics of high silicon bainitic cast steels
(Maney Publishing, 2019-01)
This study investigates the effect of chemical composition and microsegregation on the bainitic transformation of high Si cast steels at two different austempering temperatures. The advance of the bainite precipitation as ...
Constitutive models of steel under continuous casting conditions
(Elsevier Science Sa, 2003-12)
We review in this paper a series of constitutive equations that describe the behavior of steels at elevated temperatures, laying emphasis upon continuous casting processes. The different laws are situated in an appropriate ...
The Interrelation between Casting Size, Steel Grade, and Temperature Evolution Along the Mold Length and at the Strand Surface during Continuous Casting of Steel
(Taylor & Francis IncPhiladelphiaEUA, 2011)
Application of a solidification mathematical model and a genetic algorithm in the optimization of strand thermal profile along the continuous casting of steel
(Taylor & Francis IncPhiladelphiaEUA, 2005)
Microstructural and fractographic investigation of a centrifugally cast 20Cr32Ni + Nb alloy tube in the ‘as cast’ and aged states
(São Paulo, 2013)
Fracture surface and microstructure of tensile samples taken from a centrifugally cast 20Cr32Ni + Nb alloy tube were investigated in the ‘as cast’ state and after being submitted to isochronal aging at temperatures between ...
Investigation of nonmetallic inclusions in continuously cast carbon steel by dissolution of the ferritic matrix
(Elsevier Science IncNew YorkEUA, 2002)
Failure analysis of a martensitic stainless steel (CA-15M) roll manufactured by centrifugal casting. Part I: Material and fractographic characterization
(Oxford, 2014-01)
The failure analysis of a martensitic stainless steel (CA-15M) roll manufactured by centrifugal casting and used in cast glass rolling was carried out by means of traditional characterization techniques (optical metallography, ...
Characterization of the cold ductility degradation after aging in centrifugally cast 20Cr32Ni+Nb alloy tube
(ELSEVIER SCI LTD, 2009)
The mechanical properties (yield stress, ultimate tensile stress and elongation) of alloy 20Cr32Ni + Nb subject to isochronal aging at temperatures between 670 and 820 degrees C for 200 h were investigated using samples ...
Mild and severe wear of steels and cast irons in sliding abrasion
(ELSEVIER SCIENCE SA, 2009)
This paper presents the results obtained in pin-on-disk test apparatus using glass and alumina as abrasive materials, showing the rates and mechanisms of abrasive wear of 1070 and 52100 steels, and ductile and white cast ...
