| Abstract | Vertical compensation friction stir welding (VCFSW) is successfully applied to weld 7N01-T4 aluminum alloy, and effects of welding speed on joint quality are investigated. The results show that when compensation strip width is 1 mm, the defect-free joint is obtained at the welding speed of 50 mm/min and constant rotational velocity of 2000 rpm. Moreover, the intercalation lamellae structure formed in nugget zone (NZ) can reveal material flow behavior clearly. As strip width increases to 1.5 mm, it is difficult to attain sound joint. Decreasing welding speed is beneficial to surface formation of VCFSW joint. The increase of welding speed decreases tensile strength and elongation of joint. At the welding speed of 50 mm/min and strip width of 1 mm, the tensile strength and elongation of VCFSW joint are 295.7 MPa and 6.7 %, equivalent to 66 and 39.4 % of BM, respectively, while fracture surface of joint presents typical ductile fracture. The hardness distribution of joint shows typical W shape, and the hardness of NZ exhibits uniform distribution. |

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.
