Solution Strengthening and Short-Range Order in Cold-Drawn Pearlitic Steel Wires

Crystals
Pearlitic steel rods are subjected to cold-drawing processes to produce pearlitic steel wires with true strains ranging from 0.81 to 2.18. Tensile tests are utilized to attain mechanical properties of cold-drawn pearlitic steel wires.

Analysis of Fatigue Crack Paths in Cold Drawn Pearlitic Steel. [PDF]

Materials (Basel), 2015
In this paper, a fracto-metallographic analysis was performed on the cracked specimens of cold drawn pearlitic steel subjected to fatigue tests. Fatigue cracks are transcollonial and exhibit a preference for fracturing pearlitic lamellae, with non ...

Altering the microstructure of pearlitic steel using pulsed electric current [PDF]

, 2015
Pearlitic steel is widely used in many industries due to its inherent strength and toughness. It can have a tensile strength in excess of 6GPa in the cold- drawn state [1] and its properties and machinability can be altered through heat treatments, such ...

Advanced Heat Treatment of Pearlitic Rail Steel

Materials, 2023
The aim of this research is a systematic investigation of heat treatments of 60E1 profile rails made of steel R350HT, which would ensure the properties required by the standard EN 16273. Additionally, it presents a concept of cooling rails on a semi-industrial station, which will make it possible to obtain the desired properties. The dilatometric tests

SPD Deformation of Pearlitic, Bainitic and Martensitic Steels

MATERIALS TRANSACTIONS, 2023
The deformation behavior of nearly fully pearlitic, bainitic and martensitic steels during severe plastic deformation is summarized in this paper. Despite their significantly different yield stresses and their microstructures, their hardening behavior during SPD is similar.
