Functionally Graded Materials (FGMs) are comprised of a unique mixture of materials blended into specialized superalloys through AM DED. EWI has recently completed R&D to create a set of these materials for the Department of Energy and is working to develop standard methods for modeling and validating FGMs. This work is discussed in Functionally Graded...

Aluminum and advanced high-strength steels (AHSS) have been increasingly applied to automotive structural components which allow for improvements in crashworthiness without corresponding weight increases. However, these materials bring along challenges of controlling or compensating springback in design and production phases. Excessive springback causes fit and finish issues and is very difficult to eliminate or reduce...

Recent changes in Federal regulations governing high-pressure gas transmission pipelines require that pipeline operators have traceable, verifiable, and complete documentation of the pipe material comprising their pipelines. In cases where documentation of pipeline material does not meet the regulations, this physical testing must be completed on material removed from the pipeline. EWI’s material test laboratory...
