| Abstract | This study investigates the dissolution behavior of metallic substrates-Ni and IMC-Ni3Sn4 phase in molten Sn, SAC, SC, SB and SZ at 240, 270, and 300°C. The dissolution rates of the Ni substrate in molten solder follow the order Sn > SAC > SC > SB > SZ. Many the Ni3Sn4 phases with a small grain size were formed at the Sn/Ni system. Because a small grain could provide more groove to let Ni atoms dissolve in the molten Sn, the largest dissolution rate is in the Sn/Ni system. The dense Ni5(Zn, Sn)21 phase was formed in the SZ/Ni system. This dense layer inhibited the Ni atoms to dissolve into the molten solder. Thus, the SZ/Ni system has the lowest dissolution rate. The dissolution rate of the Ni3Sn4 substrate in molten solders follows the order Sn > SAC > SC > SB at 240°C and Sn > SC > SAC > SB at 300°C. There is no any IMC found in the Sn/Ni3Sn4 and SB/Ni systems. The (Cu, Ni)6Sn5 was observed in the SAC/Ni3Sn4 and SC/Ni3Sn4 systems. In the SZ/Ni3Sn4 system, the Ni5(Zn,Sn)21 phase was formed at the interface. Meanwhile, the Zn atoms diffused toward the Ni3Sn4 substrate to incorporate the sublattice of the Ni3Sn4 phase. Finally, the Ni3(Sn,Zn)4 layer was observed below the Ni5(Zn,Sn)21 phase. |

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.
