NOVELTY - Preparing a titanium-based composite material with high thermal conductivity involves mixing a ball milling titanium alloy powder and graphene nanosheets to obtain a composite powder according to a certain mass ratio, A clean and sealed envelope is prepared according to the required composite material size. The composite powder is filled into the sheath until the composite powder fills the sheath cavity. The envelope filled with the composite powder is Vacuumizd to obtain a vacuum powder envelope. The vacuum powder envelope is subjected to vacuum heat treatment. The vacuum powder envelope after the vacuum heat treatment is separated from the outside air and kept in a vacuum state. The hot isostatic pressing is performed on the vacuum powder envelope after the vacuum heat treatment. USE - Method for preparing a titanium-based composite material. ADVANTAGE - The method enables to prepare a titanium-based composite material has high thermal conductivity, improves the mechanical properties of composite materials and yield strength of the composite material.
