| Abstract | Copper alloy strip used for terminal and connector springs must often provide requisite contact forces in the harsh environments of elevated temperatures, for quite long times. A number of innovative metals and several traditional metals were tested for stress relaxation at temperatures up to 200 degrees C for up to 3000 h. Recognizing that resistance to degradation at elevated temperatures is but one facet of the requirements of a spring metal, strength and formability were also measured for each of the alloys. Yield strength was measured in the bending mode to better simulate the way stress is developed in actual spring members of terminals and connectors. Formability was determined with standard methods but, more importantly, was related to the bending strengths of the alloys. Because conductivity plays a role in material selection, it is reported for each of the materials studied. It is noted that there are copper alloys in strip form that possess sufficient strengths to provide high initial contact forces, are formable enough for sophisticated geometries, have desirable conductivities, and can provide contact forces that withstand service temperatures approaching 200 degrees C.< |

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.
