Title: Xuwei Liu: Innovator in High-Strength Steel Technologies
Introduction
Xuwei Liu is a prominent inventor based in Ganzhou, China. He has made significant contributions to the field of materials science, particularly in the development of advanced steel alloys. With a total of 2 patents, Liu's work focuses on enhancing the properties of steel to meet modern engineering demands.
Latest Patents
Liu's latest patents include innovations in high-strength and high-plasticity TWIP steel. This patent discloses a method that improves the comprehensive properties of TWIP steel through the inclusion modification with cerium (Ce) and barium (Ba) additions. The process involves fine grain strengthening and twinning nanocrystallization, which are achieved by controlling the grain size through low-temperature cold rolling, transient annealing treatment, and low-temperature tempering treatment. The addition of Ce reduces the stacking fault energy of the TWIP steel, promoting the formation of twins and their division into grains. This ultimately enhances the yield strength of the material.
Another notable patent by Liu is for rare earth die steel. This innovation involves the addition of magnesium (Mg) and boron (B) elements alongside the rare earth element yttrium (Y). The rare earth element purifies the matrix, while Mg and B regulate the grain network of chromium carbides. The inclusion of B improves the hardenability of austenite, ensuring that non-martensitic structures such as bainite do not form during cooling. As a result, this rare earth die steel exhibits high impact toughness and isotropy.
