Title Forged Ingot Niobium Technology for Accelerator Applications and Scientific Frontiers
Abstract Accelerator applications and world?s science frontier programs demand high performance and cost-effective SRF technology. Fine-grain (FG) and Large-grain (LG) ingot niobium technologies have been developed and implemented. However, forged ingot niobium technology is the focus of this presentation which is cost-effective and expected to have several technical advantages. FG niobium sheet production involves more than ten processing steps making them prone to contamination. The LG disc production cost is significantly low compared to FG niobium sheet. However, there are draw backs due to non-homogeneity of the grain boundary distribution, resulting in non-uniform mechanical properties. Medium-grain (MG) niobium disk production may be realized with a new approach/process, the disc directly sliced from the forged ingot, involves a simpler process steps contributing major production cost reduction. These discs are expected to be superior as they tend to be homogeneous with uniform sub m
