The number of point defects formed in spherical cementite and CrC inclusions embedded into ferrite (-iron) has been studied and compared against cascades in pure versions of these materials (only ferrite, FeC, or CrC in a cell). Recoil energies between 100 eV and 3 keV and temperatures between 400 K and 1000 K were used. The overall tendency is that the number of point defects — such as antisites, vacancy and interstitials — increases with recoil energy and temperature. The radial distributions of defects indicate that the interface between inclusions and the host tend to amplify and restrict the defect formation to the inclusions themselves, when compared to cascades in pure ferrite and pure carbide cells.
