摘要：

In this study, measurements of the thermal contact conductance (TCC) at the interfaces of Hastelloy C-276/Hastelloy C-276 and Hastelloy C-276/SS302 test pairs were conducted by a self-developed experimental setup based on the steady-state heat flux method. The reliability of experimental setup and method was validated by the repeated measurement of the thermal contact conductance between Hastelloy C-276 and Hastelloy C-276. In addition, the effects of contact pressure and interfacial temperature on thermal contact conductance were also discussed. This study not only provides a necessary database for the accurate numerical simulation but also lays a foundation for the optimal design of the shrink fitting process of rotor can.
