| Abstract | TiAl is brazed with Ti-Zr-Fe and Ti-Zr-Cu-Ni-Fe brazing foils at 1,323 and 1,373 K for 5 min. Ti-rich, Ti$_{3}$Al, and white blocky Ti-Zr-Al-Fe phase are found in the joint brazed with Ti-Zr-Fe filler metal at 1,323 K. Ti$_{2}$Al phase is formed with the improved brazing temperature. When using Ti-Zr-Cu-Ni-Fe filler metal, the joints are mainly comprised of Ti-rich, Ti$_{3}$Al, and Ti$_{2}$Al and white blocky Ti-Zr-Al-(Cu, Ni, Fe) phase. The joint widths and the size and amount of white blocky Ti-Zr-based phases in the center of the joints are increased when the brazing temperature is increased. And under the same brazing condition, the joint width, the size of Ti$_{3}$Al and Ti-Zr-Al-(Cu, Ni, Fe) phase in the joint brazed with Ti-Zr-Cu-Ni-Fe filler metal, are larger than that of Ti-Zr-Fe filler metal. More TiAl base metal dissolved into the joint induces the wider joint and the higher concentration of element Al in the joint, which lead to form Ti$_{2}$Al phase. Too large size compounds such as Ti-Zr-based phases and Ti$_{3}$Al would deteriorate the joint property. A lot of these phases also might have a negative effect on the joint property. |

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.
