Ultrasonic attenuation in pearlitic steel

Ultrasonics, 2014
Expressions for the attenuation coefficients of longitudinal and transverse ultrasonic waves are developed for steel with pearlitic microstructure. This type of lamellar duplex microstructure influences attenuation because of the lamellar spacing. In addition, longitudinal attenuation measurements were conducted using an unfocused transducer with 10 ...

Formation of pearlitic banded structures in ferritic‐pearlitic steels

Steel Research, 1992
The conditions for ferrite and pearlite banding in strip and plate made of structural steels were investigated. Factors found to influence the formation of banded structures were the cooling rate during the γ/α‐transformation, the former austenite grain size, and the work‐hardened condition of the former austenite.

Ortho-pearlite in silicon steels

Acta Metallurgica, 1970
Abstract A structure called porous cementite, found in steels containing silicon or aluminum, is identified as a special kind of pearlite called ortho-pearlite. It is closely related to divergent pearlite formed in steels with other alloying elements.

Friction between pearlitic steel surfaces

Wear, 2019
Abstract Experiments rubbing two pearlitic rail steel surfaces against each other were done using an axial-torsion test rig. After the experiments were completed, the surfaces were observed under stereomicroscope, and the wear debris were examined.

Fracture of steels containing pearlite

Metallurgical Transactions, 1972
The relative effects of pearlite and spherodite on ductile, cleavage, and fatigue failure are summarized. Neither the cleavage strength nor the fatigue endurance limit appear to depend directly on cementite contentper se. Spherodized steels cleave less readily than ferrite/pearlite steels.

Microstructure and Substructure of Pearlite in Hypoeutectoid Ferritic-Pearlitic Steels

Metal Science and Heat Treatment, 2017
The substructure and microstructure of pearlite in hypoeutectoid low-carbon steel 09G2S is studied using high-contrast images in a scanning electron microscope and electron backscattered diffraction. Acorrelation is established between local deviations from “ideality” in the structure of pearlite and the substructure of pearlitic ferrite.

Strengthening in low carbon pearlitic steels

Materials Science and Engineering, 1986
Abstract The microstructure-flow stress relationship has been examined in two simple ferrite-pearlite steels. As in fully pearlite steels, a Hall-Petch equation was shown to be applicable, when care is taken in obtaining the appropriate mean slip distance in ferrite for each microstructure.

Micromechanical modeling of ferritic/pearlitic steels

Materials Science and Engineering: A, 2002
A two-dimensional micromechanical model based on the Voronoi algorithm is presented to model two-phase ferritic/pearlitic steels. Special care is taken to generate periodic grain structures as well as periodic finite element meshes. The model is evaluated by generalized plane strain finite element calculations, periodic representative cells are ...
