Abstract In linepipe steels, strength and toughness are tailored not only by designing microalloyed compositions but also by controlling hot working process, in order to obtain homogenized and refined microstructure. In the present study, microalloyed steel akin to X80 grade linepipe composition was investigated to examine the effect of hot deformation conditions on the flow behaviour. The isothermal hot compression experiments were carried out on Gleeble™ 3800 thermo-mechanical simulator, with varying strain rates of 0.1, 0.5 and 1 s$^{−1}$, at different temperatures of 950, 1000, 1050 and 1100 °C. The material was homogenized at 1200 °C and cooled to deformation temperature prior to hot compression. Dynamic recrystallisation (DRX) parameters were estimated from the observed flow behaviour. Based on the analysis, a correlation was obtained that described the DRX behaviour of the studied steel. The apparent activation energy (Q$_{def}$) for DRX was determined as 480 kJ/mol. This value was considerably higher than that for plain C–Mn steel and gave a favourable DRX condition for grain refinement in linepipe steels.

About National Digital Library of India (NDLI)
NDLI logo

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
