| Abstract | Effect of reversion of strain induced α′ martensite on mechanical properties of an austenitic stainless steel has been examined. The α′ martensite formed by cold rolling (40%) at 0 °C has been reverted to austenite by carrying out annealing in the temperature range of 300–800 °C for 1 h. Microstructural investigation has demonstrated the enhanced reversion with increasing annealing temperature without any perceptible grain growth up to 800 °C. X-ray diffraction (XRD) analysis has revealed that 40% cold rolling has resulted in the formation of 32% martensite. The residual martensite content has been found to be about 8% after reversion at 800 °C. Different stages of reversion behavior has been examined by differential scanning calorimetric measurement. The variation of dσ/dε with ε is examined to identify different stages of work hardening of the investigated steel. Both tensile strength and percent elongation values increase with increasing annealing temperature up to 500 °C. Beyond that annealing treatment results in the drop of tensile strength value with the consequent increase in percent elongation. Attractive strength–ductility combination (22.80 GPa%) has been achieved after annealing of the 40% cold deformed specimen at 800 °C for 1 h. The fractographic observation corroborates the tensile results. |

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.
