Summary

These novel composites are of particular interest for their high melting points, low overall densities and good corrosion and oxidation resistance, giving these composites a high potential for applications as engine valves or break discs. Furthermore, the Ti-based systems have a high bio-compatibility [9] and are therefore favorable for bone replacements. Based on high-energy milling, a new low-cost production route for these alloys has been developed, which allows for variation of the metallic phase or the ceramic volume fraction in a wide range. In this way, the properties of the composites can be tailored to suit the desired applications.
