As people's understanding of the relationship between material properties, composition, organization, and various influencing factors deepens, material development has gradually been quantified. In recent years, with the development and application of computer technology, breakthroughs have been made in the quantification of alloy research and development. New alloy design methods have been proposed, and gratifying achievements have been made in the development of new alloys, achieving the design of new alloys according to specified properties. For example, the Japan Institute of Metal Materials used alloy design methods to redesign the American M247 directional alloy, increasing the cobalt and chromium content and reducing the carbon and titanium components. The resulting directionally solidified TMD-5 alloy has much higher performance than M247 alloy.
