| Abstract Scope |
Electric-field assisted sintering (EFAS) is an advanced manufacturing method for efficient consolidation and processing of ceramic and metal materials. This is due to direct rapid heating of the materials and molds through Joule heating. The technique does have limitations though as it is traditionally a batch process and suffers from scale up difficulties. Researchers at Idaho National Laboratory designed and constructed a continuous EFAS system (CEFAS) whereby rollers are heated using the same physics used in batch style systems but can apply unique stress states through a rolling, compressive action. Its design creates highly localized electrical, thermal, and mechanical process parameters for continuous samples of limitless length. The system details, design process, control system overview, and modeling work will be discussed along with cursory characterization of sample materials that have been processed. |
