| Abstract | Summary form only given. With the development of electronic productions based on lead-free solder, SnAgCuRE as a special lead-free solder alloy in our country, which possess better microjoining technological property and higher mechanical property, has been the hot-point of the microjoining research field. To reduce the manufacturing costs of SnAgCuRE lead-free solder alloy and improve or increase its creep and fatigue properties of soldered joints, with reference to the commercial employed Sn3.8Ag0.7Cu solder, taking Sn2.5Ag0.7Cu0.1RE lead-free solder alloy with lower Ag content as a research object, based on the research of microstructure. mechanical and physical performances and wettability of Sn2.5Ag0.7Cu0.1REXNi solder alloy with lower Ag content fabricated by vacuum condition in this paper. And the creep behavior and its rupture life of Sn2.5Ag0.7Cu0.1REXNi soldered joints were separately investigated under constant temperature by a single shear lap creep specimen with a 1 $mm^{2}$ cross sectional area. The result shows that the performances of Sn2.5AgO.7Cu0.1RE solder alloy and its creep properties of the solder joints can be improved with adding Ni, especially the elongation of Sn2.5Ag0.7Cu0.1RE0.05Ni can be obviously improved without degradation its strength, which is 1.4 times more than that of the commercial employed Sn3.8Ag0.7Cu solder alloy. Accordingly the creep rupture life of its solder joints is the longest , which is 13.3 times more than that of Sn2.5AgO.7Cu0.1RE, and is far superior to that of the commercial employed lead-free solder Sn3.8Ag0.7Cu. Therefore, Ni amount added to the Sn2.5AgO.7Cu0.1RE solder alloy under 0.05% is proper. The results are helpful for the practical application of Sn2.5Ag0.7Cu0.1RE lead-free solder. |

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.
