  We propose cost-effective production of medium grain (MG) niobium (Nb) discs
directly sliced from forged and annealed billet. This production method
provides clean surface conditions and reliable mechanical characteristics with
sub-millimeter average grain size resulting in stable SRF cavity production. We
propose to apply this material to particle accelerator applications in the
science and industrial frontiers. The science applications require high field
gradients (>~40 MV/m) particularly in pulse mode. The industrial applications
require high Q0 values with moderate gradients (~30 MV/m) in CW mode operation.
This report describes the MG Nb disc production recently demonstrated and
discusses future prospects for application in advanced particle accelerators in
the science and industrial frontiers.
