Magnesium diboride is a new intermetallic superconductor with unique properties. Hot isostatic pressing (HIPing) is one of the most effective methods for the processing of bulk MgB2 from powder with excellent superconducting and mechanical properties. A high density of lattice defects is very desirable to increase the density of pinning centers which are crucial for high magnetic field applications. A combination of shock loading and subsequent hot isostatic pressing was employed to modify the microstructure and properties of bulk MgB2 as was successfully demonstrated earlier with another intermetallic material — titanium aluminide. Superconducting and mechanical properties, including elastic constants and Q measured with the DRS RUS method, of shock+HIPed material is presented and compared with properties of “as is” HIPed Alfa Aesar MgB2 powder.
