Description

technical field [0001] The present invention relates to nano-titanium silicon compound, specifically, a face-centered cubic structure Ti 3 Si nanoparticles and methods for their preparation. Background technique [0002] Titanium-silicon alloys have attracted increasing attention due to their good casting properties and mechanical properties. Metastable materials such as nanocrystalline and amorphous titanium-silicon alloys have low density, high strength, high temperature resistance, oxidation resistance, It is expected to be more widely used in important fields such as microelectronics, aerospace, and national defense due to its excellent electrical and thermal conductivity. At present, the research on titanium-silicon alloy nanomaterials mainly focuses on Ti 5 Si 3 aspect, especially for adding Ti 5 Si 3 The changes of thermal expansion coefficient, Young's modulus, hardness, creep strength, fracture toughness, etc. of the latter alloy are deeply discussed. However,...
