| Abstract | 0.27C-1.97Cr-1.65Mn-0.30Mo-0.21Ni steels produced by thermomechanical processing were rolling contact fatigue tested in the elastohydrodynamic lubricating condition at the rotating speed of 8,000 rpm under the applied load in the range of 25–100 kgf. A mixture of lower bainite and martensite was formed during thermomechanical processing, and it was found in transmission electron microscopy that fine lower bainite was formed by splitting in two after formation of martensite. The zone of maximum shear stress was found to be 195.0–339.3 μm in depth from the contact surface by comparing the regions of hardness increase, microstructural change and the contact width during rolling contact fatigue. Resistance to crack initiation during rolling contact fatigue is the main reason for improved fatigue life. This is confirmed from the result that the shortest fatigue life was shown in the specimen with the largest crack length and crack depth. |

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.
