ExtremeMat: Quantification of the Effect of Microstructure and Composition on the Creep Rupture Life of Steels: Laurent Capolungo1; Arul Kumar1; Ricardo Lebensohn1; Andrea Rovinelli1; Paul Christodoulou2; Yuki Yamamoto3; 1Los Alamos National Laboratory; 2UCSB; 3ORNL
Structural steels utilized for power generation applications are subjected to complex loading conditions (e.g. stresses, temperatures). A robust knowledge of the evolution of the performance steels, both austenitic and ferritic, with service conditions relies on the degree to which one can establish firm bridges between the microstructure, composition and material performance: such is one of the primary goals of the consortium ExtremeMat. To quantify the impact of microstructure on the material creep rupture life, we introduce a new spectral based model predicting the primary, secondary and tertiary creep response of ferritic and austenitic steels. The framework is found to satisfactorily predict the effects of temperature and stress on the creep rupture life rupture of 347H (austenitic) and Gr91 (ferritic) steels. Finally, leveraging the numerical efficiency of the EVPFFT platform the roles of initial dislocation and precipitate content on the creep rupture life of the material is studied.

Advancing ICME Technologies Via Strategic Collaboration while Bridging the Gap Between Academia and Industry: Ida Berglund1; 1QuesTek Europe AB
The benefits to industry in applying ICME are many, including a science-informed understanding of the challenges observed in material manufacturing, rapid optimization of chemistry and heat treatment, and an accelerated qualification of new materials enabling improved component performance. This presentation will exemplify how QuesTek has leveraged its ICME technologies to understand and worked to resolve the most pressing materials related issues to combine manufacturability and performance in various alloy systems. Emphasis will be placed on how QuesTek utilize expertise and interact with entities across the value chain, from producers and manufacturers to end-users, and in collaboration with research institutes and universities. This workflow inherently helps to bridge the gap between academia and industry. Technical examples from collaboration projects in Europe and USA will be presented, and general challenges discussed.
