| Abstract | The method of ultrasonic forging allows creating on a surface a hardened layer, which does not have a marked interface with a substrate. The presence of such a layer on a surface should not result in considerable effects of localization, but at the same time, due to high-density of defects in a near-surface layer in control of homogeneous development of plastic deformation as a whole according to specimen. Low-carbon steel ST3/sup 0/ was used. Hardening the surface was conducted on the one hand of a specimen under conditions of ultrasonic burnishing. Under used treatment conditions the depth of study of a near-surface layer revealed according to analysis of a microhardness, amounted to 180 microns. The tests for single-axis static stretching were conducted on the test facility "IMASH 20-7" with speed of stretching of 0.05 mm/min. With the usage of an optical and television measuring complex "TOMSC-1", the principle of operation which one is based on computer processing of the optical images of a surface, fields of vectors of displacement were plotted. The analysis of distribution of vectors of displacement constructed at overseeing for a surface of a lateral face was conducted. The character of plastic deformation at a mesoscale level was investigated. |

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.
