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.

Improving hot-ductility of 310 stainless
JOM, 1957Under some conditions of manufacture, austenitic stainless steels exhibit a tendency to hot-crack during fabrication. Hot-cracking has been observed in casting, heating for working, ingot breakdown, hot-rolling, tube-piercing, and other hot-forming operations. It has been particularly troublesome in both the weld and heat-affected zones of welded heavy

Boring a Hot Trend with Ductile‐Iron
Opflow, 2003This article reports that the Orlando Utilities Commission (OUC) has found success using conventional bell‐spigot and “bell‐less” ductile‐iron pipe joints for installation by trenchless methods. Due to a proactive pipeline renewal and replacement program, OUC has investigated various trenchless methods to install new transmission and distribution lines,

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.

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

Metal Science and Heat Treatment, 2009
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.

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 Working of Ductile Iron Alloyed With Molybdenum
Canadian Metallurgical Quarterly, 2000On a forme a chaud, a 1050 °C, des moulages de fonte nodulaire contenant jusqu'a 0,5% de Mo, provenant de moules en sable et de moules permanents (SMC & PMC), avec reduction totale allant jusqu'a 90%. On a pu laminer la plupart des moulages avec une grande reduction par passe (36% en moyenne), jusqu'a une reduction totale de 75%, sans fissure serieuse,

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.
