| Abstract | An austenite-martensite class of stainless steel having 6Ni-16Cr (wt%) has been developed with a view to have fully austenite structure at the austenitizing temperature and a transformation structure containing austenite and martensite upon quenching. The steel has been processed through two different melting routes, vacuum melting route and air melting route. Results of both the routes were found to be similar. Nearly 50% metastable austenite is retained after quenching, which transforms further during cold deformation and sub-zero treatment. Tensile strength of 1370 MPa with 18% elongation and 1015 MPa with 11% elongation were achieved at room temperature and at 773 K respectively. Excellent tensile strength of the order of 1800 MPa and 21% elongation at 77K have been attributed to transformation induced plasticity (TRIP) occurring during processing and testing. |

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.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
