Ray Ranjan, Scott Donald W: Castings of metallic alloys fabricated in anisotropic pyrolytic graphite molds under vacuum. Santoku America, Ray Ranjan, Scott Donald W, VENTURINO Anthony P, November 28, 2002: WO/2002/095080

Molds (10) are fabricated having a substrate (14) of high density, high strength ultrafine grained isotropic graphite, and having a mold cavity (16) coated with pyrolytic graphite (18). The molds may be made by making the substrate (main body) of high density, high strength ultrafine grained isotrop ...
