This invention discloses a method for recycling titanium alloy recycled materials based on hot isostatic pressing (HIP), belonging to the field of titanium metallurgy. The method includes the following steps: First, titanium alloy recycled materials with different oxygen contents are accurately calculated and mixed to obtain a homogeneous mixture.
