Title: Innovations of Weihao Cai in High-Strength Steel
Introduction
Weihao Cai is a notable inventor based in Ganzhou, China, recognized for his contributions to the field of materials science, particularly in the development of advanced steel alloys. With a total of two patents to his name, Cai has made significant strides in enhancing the properties of steel through innovative methods.
Latest Patents
Cai's latest patents include the development of high-strength and high-plasticity TWIP steel and a preparation method thereof. This invention focuses on improving the comprehensive properties of TWIP steel by incorporating Ce and Ba for inclusion modification, fine grain strengthening, and twinning nanocrystallization. The controlled grain size is achieved through low-temperature cold rolling, transient annealing treatment, and low-temperature tempering treatment. The addition of Ce reduces the stacking fault energy, promoting twin formation and division into grains, which enhances yield strength and results in a high-strength, high-plasticity TWIP steel.
Another significant patent by Cai is the rare earth die steel and its preparation method. This invention involves the addition of Mg and B elements alongside the rare earth element Y, which purifies the matrix and optimizes grain network chromium carbides. The B element improves the hardenability of austenite, ensuring that non-martensitic structures like bainite do not form during cooling. Consequently, this results in rare earth die steel characterized by high impact toughness and isotropy.
Career Highlights
Weihao Cai has worked at prominent institutions, including Jiangxi University of Science and Technology and Guorui Scientific Innovation Rare Earth Functional. His work in these organizations has contributed to his expertise in materials science and innovation in steel production.
