Today's fast developing technological based society places ever accelerating demands for new materials and materials processing methods. Leading edge fields as diverse as biomedical tissue engineering, quantum device, optical and magnetic information storage technology as well as immobilization of actinides, all require nanoscale engineering through controlled materials modification. The evolution of these advances from the research science stage to the industrial applications is a particular challenging task. Amongst the beam processing methods for materials modification MeV ions occupy a unique place. They interact strongly with both the atomic and electronic structures of the target material to produce a broad plethora of modifications with well-defined penetration characteristics. These modifications can be precisely controlled because MeV ion can be steered and focused using electrostatic and magnetic fields and also close process control is possible because their delivery can be monitored electrically. Materials engineering with MeV ions is described in this chapter with some practical examples of their use in advanced materials.
