|Abstract||Experiments were carried out to study the effect of the second phase of metallic compounds on the Work Softening'' phenomenon in Al--Fe, Al--Si, Al-- Mn, and Al--Li alloys. When particles of metallic compounds were dissolved by quenching after solution treatment so that the ingot was in the state of super- saturated solid solution or eutectics, the Work Softening'' phenomenon was not observed in the sheet obtained from this ingot. On the other hand, the Work Softening'' phenomenon was observed in the sheet produced by a process of preheating the ingot followed by an intermediate heat treatment to precipitate a large amount of metallic compounds, when light rolled after final annealing at the temperature of the softening stage. The finer the precipitated particles were, the more distinctively the Work Softening'' phenomenon was observed with no connection with natural or artificial aging after light rolling. Regarding the process of Work Softening'' phenomenon, it cannot be explained by the Cottrell mechanism. Therefore a more thorough investigation in the light of the sub-grain formation by dislocation rearrangement may be required.|

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.
