摘要
Failure due to crack propagation is the crucial failure mode of the optical quality polycrystalline diamond disks, which are used as safety and vacuum barriers in the electron cyclotron systems of nuclear fusion devices. This paper reports on the characterization of preliminary polycrystalline diamond samples for experimental measurements of the diamond fracture toughness by the double-torsion method.
