Research progress of high-temperature amorphous alloys

<p indent="0mm">Amorphous alloys have unique mechanical, physical and chemical properties due to their disordered atomic arrangement. However, a thermodynamic metastable state, the amorphous alloys would occur structural relaxation and even crystallization with the environment changes, lead to the most parts of the amorphous alloy are limited application far below the high service temperature. Compared with the conventional amorphous alloys, high-temperature amorphous alloys (the glass transition temperature is usually higher than <sc>1000 K)</sc> which have much higher thermal stability, mechanical properties, corrosion resistance and antioxidant properties, are expected to be applied in the extreme environments, such as high temperature and strong corrosion environment. This review paper expounds the remarkable progress of high-temperature amorphous alloys in the glass formation ability, mechanical properties, chemical properties and other performance. The different performance of high-temperature amorphous alloys previously reported are comprehensively appraised and discussed. The challenges and future development trends of high-temperature amorphous alloys are also discussed to provide the reference for the application of this high performance metals.
