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 MICROALLOYED STEELS
, 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 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

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 ...

Effect of thermal history on hot ductility of steel
, 1998 One of the major quality problems encountered in continuous casting is the formation of transverse cracks, which is partly due to the poor hot ductility of the cast steel. In this work, high temperature tensile testing is used to determine the hot ductility of a Nb-Ti and Ti-B microllayed steels.
