| Abstract | Manganin is the trademark name of the alloy Cu86Mn12Ni2. Despite its frequent usage in manufacturing processes, literature data are scarce particularly at higher temperatures. This work presents a set of thermophysical data of this alloy in a temperature range above its classic area of application up to the end of its liquid phase. For investigating the alloy, four examination setups were employed. Using differential thermal analysis, solidus and liquidus temperatures were obtained. In the solid phase, the electrical resistivity as a function of temperature was determined by a four-point probe positioned in a furnace. Thermal expansion was measured with a high-resolution two-beam laser dilatometer based on Michelson-interferometry and thereby density was calculated. The liquid state was investigated using a $$μ $$ s-ohmic-pulse-heating setup. Wire-shaped specimens were resistively volume heated as part of an electrical discharge circuit. Measured quantities were the current through the specimen, the voltage drop along the specimen, the surface radiance by a pyrometer, and the thermal expansion with an adapted CCD camera system. On the basis of these measurements, temperature-dependent thermophysical properties of enthalpy, isobaric heat capacity, electrical resistivity, and density are obtained. Additionally the thermal conductivity and thermal diffusivity are estimated in the high-temperature range applying the Wiedemann–Franz law. |

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.
