Influence of carbon on hot ductility of steels
Materials Science and Technology, 1986AbstractHot ductility, measured by reduction in area, has been determined over the temperature range 550–950°C for a series of plain C–Mn steels having the same base composition except for the carbon content, which was in the range 0·04–0·65 wt-%. A ductility trough was obtained for all the steels and minimum ductility values were similar.

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.

Hot ductility of steel 09G2S is studied in a temperature range of 600 – 1000°C on the branch of cooling after heating to a high (1150°C) temperature. The causes of the nonmonotonic variation of the hot ductility are determined, and ways for removing the ductility dip are suggested.

Influence of calcium on hot ductility of steels
Materials Science and Technology, 1989AbstractThe hot ductility of C–Mn–Al and C–Mn–Nb–Al steels with and without calcium additions have been examined over the temperature range 700–1000°C both after solution treating at 1330°C followed by cooling to the test temperature and directly after casting. Calcium additions invariably improved hot ductility. For hot rolled plate reheated to 1330°C

Hot Ductility of DSS and Its Microstructure Observation During Hot Deformation
Journal of Iron and Steel Research International, 2013Abstract By selecting several typical duplex stainless steels (DSS), i. e., 00Cr22Ni5Mo3N, 00Cr21Ni2Mn5N and 00Cr25Ni7Mo4N, as research materials, hot ductility characteristic of DSS was studied by thermal simulation method and microstructure evolution during hot compression was observed through TEM.

Hot ductility of steel 08Kh18N10T
Metal Science and Heat Treatment, 2011Hot ductility of steel 08Kh18N10T is studied on heating and cooling in the range 600 – 1050°C with a deformation rate of 3.3 × 10-3 sec-1. Reasons are detected and explained for the occurrence of steel ductility peaks in heating ad cooling branches of dependences on test temperature. Recommendations are given for a forming regime.

Hot Ductility of 20Cr13 Steel at High Temperature
Materials Science Forum, 2017Hot 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 leaded free-cutting steels
Metallography, 1984Abstract The hot ductility of three as-cast low carbon steels with similar volume fractions of inclusions, but with Mn/S ratios varying from 2.9 to 4.4, has been studied by hot torsion testing in an inert atmosphere at temperatures from 900° to 1250°C. Ductility, measured as equivalent surface strain to fracture, showed scatter for repeat tests of up

Hot ductility of an austenitic and a ferritic stainless steel
Materials Science and Technology, 1997AbstractThe influence of strain rate and grain size on the hot ductility of an austenitic and aferritic stainless steel has been examined. Samples were cooled from the austenitising temperature to temperatures in the range 1000 to 700°C and tensile tested at strain rates in the range 10−1 to 10−4 S−1.
