Abstract Scope |
Many engineering applications currently seek to implement additively manufactured alloys in moderate to high temperature environments. In some cases, these alloys are directly exposed to combustion processes with a potential for severe environmental degradation alongside relatively large mechanical loads. While traditional test methods seek to understand a singular material behavior under controlled conditions, in reality these effects are often highly coupled and require a holistic multifunctional test method to understand the role of environmental degradation on the system. Here a test method for extreme environments coupling highly transient thermal loading with heating rates on the order of 10,000 °C/min, heat fluxes on the megawatt scale, and a tunable continuously varying combustion environment is highlighted. The impact of this environmental degradation on alloys and coated alloy systems is explored in this context with the potential for coatings to extend the useful temperature range of both traditional and additively manufactured components demonstrated. |
