Description
Summary:TiAl alloys are regarded as ideal lightweight structural materials above 600 °C and show remarkable application prospects in the field of aerospace materials. However, many potential TiAl alloy engineering applications have been limited by their low room-temperature tensile plasticity and insufficient high-temperature capability. Composite technology is an effective method for enhancing the comprehensive properties of TiAl alloys. In this paper, recent research progress in TiAl matrix composites is reviewed to highlight the scientific and technological investigation of TiAl matrix composites with excellent properties. The content includes four aspects of TiAl matrix composites: reinforcement selection, configuration design, interfacial microstructure, and processing technology. The aim of this work is to provide a reference for the preparation and research of TiAl matrix composites and open up a novel design direction for TiAl matrix composites with excellent comprehensive properties.
