High temperature micromechanical behavior of Ti2AlN particle reinforced TiAl based composites investigated by in-situ high-energy X-ray diffraction

The high-temperature compressive property of Ti2AlN/TiAl composites, which are promising lightweight materials for high-temperature applications, was investigated. In situ high-energy X-ray diffraction (HEXRD) was utilized to analyze the micromechanical behavior at different deformation stages. It i...
