Investigation of the Properties of Titanium-Carbon Hybrid Alloys.
Abstract
The effects of 6% aluminum additions on the compressive properties and microhardness of titanium-titanium carbide composites were investigated. Composites containing 40-50% TiC by volume were produced using standard casting procedures from the melt. Enhanced strength of Ti-TiC composites at room temperature and elevated temperatures upon Al additions was found. Strengthening mechanism was also studied. The tensile properties of Ti-TiC composites was most sensitive to the size and distribution of TiC particles. Tensile properties with different TiC size which was controlled by cooling rate during melting were studied. Results show that 50% improvement of ultimate tensile strength could be achieved by microstructure refinement. Titanium-base alloys are a potential candidate for space applications because of their light weight, high specific modulus, high specific strength, and good corrosion resistance. The TiC system reinforced metal-matrix composites were produced by traditional ingot metallurgy. The use of this metallurgical method has been developed in an attempt to improve mechanical properties through the presence of a ductile metal matrix. Good strength and ductility have been achieved in compression.
