With a total of 2 patents, his work has garnered attention for its innovative approaches and practical applications.

Latest Patents

One of Bierstine's latest patents is for a method of Hybrid Induction Skull Melting. This invention involves placing a solid charge of metal or alloy in a crucible melting chamber, which is defined by a monolithic refractory tubular sleeve on a water-cooled metallic base. An energizing induction coil is used to inductively heat the solid charge to a molten state, forming a skull of solidified metal or alloy on the inner surfaces of the sleeve and base. This method allows for the reuse of the crucible in melting another solid charge after the molten charge is removed.

Another notable patent is for Ultra Low Sulfur Superalloy Castings and Method of Making. This invention provides directionally solidified superalloy components with a bulk sulfur concentration of less than 1 part per million by weight. The process involves vacuum melting a charge to form a superalloy melt, desulfurizing the melt with a calcium-bearing agent, and casting the melt to produce components with significantly improved oxidation resistance.
