Professor Liu develops an advanced aerospace material.

Effort-less Fly to the Sky

An advanced material developed by City University of Hong Kong (CityU) and Nanjing University of Science and Technology (NJUST) holds great promise for the aerospace industry.

The new material's chief quality is its improved capacity for heat resistance, its high tensile strength and low density. The new material can withstand temperatures of up to 900°C and could replace the use of Ni-based super-alloys.

The development team is led by Professor Liu Chain-tsuan, University Distinguished Professor at CityU, and Professor Chen Guang from NJUST.

The new titanium-aluminum nickel-base (TiAl+Nb) single crystal alloy created by the team can be used in turbine engines used on aircraft. It not only boosts the efficacy of an airplane, it significantly reduces noise and environmental pollution.

The new material is important to this industry because of its heat resistance. When an airplane's turbine engine turns, it produces extremely high temperatures and uses a lot of fuel.

Professor Liu's achievement has attracted much attention in academic circles and has been published as a cover story in the internationally acclaimed journal Nature Materials.
