Title: Innovations by Donald Trostle in High-Temperature Materials
Introduction
Donald Trostle is an accomplished inventor based in Herndon, VA (US), known for his significant contributions to the field of high-temperature materials. He holds 2 patents that showcase his innovative approaches to manufacturing refractory materials and high-temperature alloy parts.
Latest Patents
Trostle's latest patents include a "Near net shape combustion driven compaction process" and a "refractory composite material for high temperature applications." The near net shape refractory material is produced through a combustion-driven compaction process. In this method, a gas mixture is combusted, driving a piston or ram into a die filled with refractory material powder. This process compresses the powder into a near net shape while pre-compressing it to remove trapped air. The forces during compression can reach 150 tsi or more, and the entire loading occurs within several hundred milliseconds. After compression, the shaped refractory part is sintered in a hydrogen environment, resulting in components with minimal scrap metal. The apparatus used for this process is compact, similar in size to a telephone booth, and can be easily moved with a standard forklift.
The second patent focuses on the "near net shape fabrication of high temperature components using high pressure combustion driven compaction process." This innovative method forms high-temperature alloy parts from fine metallurgical powders. The powders are mechanically blended and placed in a die, where a piston compresses them after filling the chamber with a mixture of CH4 and air. Igniting the gas drives the piston into the cavity, producing pressures of about 85 to 150 tsi, compacting the powders into a near net shape alloy part that is ready for sintering at 2300° C without shrinking. The alloy parts consist of various combinations of Re, Mo-Re, W-Re, and other high-performance materials.
