Progress in research of in鄄situ MAX phases reinforced TiAl matrix composites is reviewed in this pa鄄
per. The phase structures and properties of MAX phases, in鄄situ technologies and synthesis mechanism of the compos鄄
ites are introduced. The microstructures, interface structure and mechanical properties of MAX/ TiAl composites are
also summarized. At last, the potential for application of the composites is introduced.
