Title: Heung Sub Song: Innovator in Tungsten Heavy Alloys
Introduction
Heung Sub Song is a notable inventor based in Daejon, South Korea. He has made significant contributions to the field of materials science, particularly in the development of tungsten heavy alloys. With a total of 4 patents to his name, his work has advanced the understanding and application of these materials in various industries.
Latest Patents
One of his latest patents is a sintering method for tungsten-nickel-manganese type heavy alloy. This innovative method involves controlling the deoxidization of tungsten and nickel under an inert atmosphere. It also includes transitioning to a hydrogen atmosphere at elevated temperatures, allowing for the simultaneous deoxidization of tungsten, nickel, and manganese. This process results in the fabrication of a sintered heavy alloy with a 100% relative theoretical density. Another significant patent is a fabrication method for tungsten heavy alloy. This method entails first creating a green compact or a sintered body composed of tungsten and other elements, excluding manganese. Manganese is then applied, and the tungsten heavy alloy is sintered, preventing pore formation due to the oxidation of manganese. This results in a tungsten heavy alloy achieving a non-theoretical density of 100%.
