Abstract
The ability to design vehicles capable of reaching hypersonic speeds has become a necessity to satisfy industry requirements, hence requiring the need for better understanding of creep behavior of materials. Although the steady state creep of metals has been analyzed rigorously, there is little known about transient creep of many metals. Understanding transient creep behavior of metals is crucial in analysis and design of short term hypersonic flight applications. Hence, a transient creep analysis of 304SS, Al7075-T6, Al2024-T6, Inconel 625, Inconel 718, and Rene N4 is carried out focusing on the microstructural behavior of these metals undergoing high temperature operating conditions. In doing so, the material properties that were unknown in literature were determined by parameter fitting techniques using existing steady state experimental data and also previous parametric studies determining critical parameters affecting strain values. A transient creep deformation map for each metal is produced including the required design space of the application.
