HOT DUCTILITY OF MICROALLOYED STEELS [PDF]
, 2008 The loss in ductility experienced by microalloyed steels at temperatures generally ranging from 700 to 1100°C is a widely studied subject in steel research. The hot ductility behaviour of steels is usually measured through the reduction of area of the samples after hot tensile tests performed up to fracture.

Effect of boron on the hot ductility of 2.25Cr1Mo steel
Materials Science & Engineering A: Structural Materials: Properties, Microstructure and Processing, 2003Abstract The effect of boron on the hot ductility of 2.25Cr1Mo steel is investigated by means of a Gleeble 2000 thermomechanical simulator. There is a trough in the hot ductility–temperature curve, which is located between 1000 and 700 °C. The ductility trough shifts to lower temperatures with increasing boron content and the hot brittle range ...

Hot Ductility of 20Cr13 Steel at High Temperature
Materials Science Forum, 2017 Hot ductility of 20Cr13 steel at high temperature was investigated through tensile test. The main phases of the steel in temperature range of 600-1400 °C were calculated with thermodynamic software. The fracture morphologies and microstructure were observed by scanning electron microscopy.

Hot ductility of medium carbon steel with vanadium
Materials Science & Engineering A: Structural Materials: Properties, Microstructure and Processing, 2016Abstract Hot ductility of medium carbon steel containing 0.52 wt% of carbon and 0.11 wt% of vanadium was investigated using a hot tensile test performed up to fracture. The hot ductility was evaluated by measuring the reduction of area of the fractured specimens, which were strained at a variety of test temperatures in a range of 600–1100 °C at a ...

Hot ductility behavior of boron microalloyed steels
Materials Science & Engineering A: Structural Materials: Properties, Microstructure and Processing, 2007Abstract The current study analyses the influence of boron contents (between 29 and 105 ppm) on the hot ductility of boron microalloyed steels. For this purpose, hot tensile tests were carried out at different temperatures (700, 800, 900 and 1000 °C) at a constant true strain rate of 0.001 s −1 . In general, results revealed an improvement of the hot

Canadian Metallurgical Quarterly, 2001
AbstractFour tool steels (A2, D2, M2 and W1) representing a wide variety of compositions (and carbide content) were hot deformed in torsion between 900 and 1200 °C at strain rates of 0.1, 1 and 4 s−1. Carbides contribute to an increase in strength but to a lower ductility.

Ductility of Microalloyed Steels during Hot Deformation
Materials Science Forum, 2010The ductility behaviour experienced by steels for linepipe (LP) applications in a temperature range generally from 700°C to 1200°C is a widely studied subject in steel research, especially for its implication on cracking during continuous casting and rolling.

Fracture and ductility in hot torsion of Nickel
Metallurgical Transactions, 1971Fracture of Nickel 270 under conditions of warm working and hot working was studied using a hot torsion testing device. Under all conditions, fracture initiates as wedge-type cracks at the peak on the torque-twist curve. A hot fracture initiation criterion is proposed based on the initial deformation conditions.

Causes of the hot ductility drops of steels
Russian Metallurgy (Metally), 2014The effect of conditions of continuous casting and hot rolling of steel on the high-temperature ductility of a microalloyed pipe steel of strength class Kh42 and 17G1S-U steel is studied. A Gleeble-3800 thermomechanical facility is used to perform physical modeling of the hot ductility of steel.
