High-performance, low-cost titanium metal matrix composites

The milled powder was then sintered at low temperature and low pressure. An in-situ precipitation occurred involving a fine and well dispersed distribution of titanium carbide in a titanium matrix. Depending on the starting composition, the volumetric quantity of titanium carbide was between 23 and 31 vol%. Despite the high ceramic loading, all of the samples could withstand tensile loading with distinct plastic deformation. The best samples showed a yield stress of 1013 MPa, Young׳s modulus of 137 GPa, an ultimate tensile stress of 1181 MPa and a strain at fracture of 5%. These results were obtained without any other additional heat treatment or hot deformation step.
