Radiation damage of TiAl intermetallic alloys

TiAl intermetallic alloys with ordered structures for nuclear applications are examined based on recent experimental results. Ti-Al intermetallic alloys are better irradiation resistance compared with that of metallic materials like austenitic stainless steels; no degradation in tensile properties and very slow development in microstructure under irradiation including swelling. The materials with these attractive properties along with inherent physical ones are one of the candidate materials for the next generation nuclear machines, although these are not yet matured as engineering materials.
