Abstract Scope |
Austenitic stainless steels are commonly used in power generation and other high-temperature structural applications that are subjected to elevated temperatures over long service lives. Precipitation of embrittling phases such as sigma, represents one of the potential degradation mechanisms austenitic stainless steels, leading to the deterioration of mechanical properties during service. Understanding the impact of the wire arc additive manufacturing process (WAAM) on the formation of sigma phases on austenitic stainless steels will help implement WAAM as a reliable method for advanced manufacturing of power generation components. In this presentation, we will discuss the influences of sigma phase formation, as well as feedstock composition, on the creep behavior of wire arc additive manufactured stainless steels such 316L, 316LSi, 316H, and 16-8-2 at 650 °C. The creep behavior of WAAM samples is compared to wrought forms to provide insight into the outlook of using WAAM for high temperature structural components. |
