Latest Patents

Liu's latest patents include two groundbreaking inventions. The first is an "Adjustable Deforming Composite Structure Based on Hydrogen-Induced Expansion Effect and Preparation Method Therefor." This invention describes a composite material that can undergo reversible shape changes when exposed to hydrogen and heat. The hydrogen-induced expansion effect allows metals to absorb hydrogen, leading to volume expansion. When the hydrogen partial pressure is reduced or the temperature is increased, the metals revert to their original shape, enabling intelligent shape adjustments at medium to high temperatures.

The second patent is a "Method for Promoting Densification of Metal Body by Utilizing Metal Expansion Induced by Hydrogen Absorption." This method focuses on enhancing the densification of metal bodies by leveraging the volume expansion effect produced by hydrogen absorption. By introducing hydrogen into a closed mold filled with a hydrogen absorption expansion material, the method effectively eliminates residual pores in metal materials, thereby improving their properties.
