Abstract
Transient Plastic Phase Processing (TPPP) is an innovative reactive processing technique for net-shape, in-situ, manufacturing of fully dense ceramic-ceramic composites [1,2]. In TPPP, a particulate mixture of a "soft" transient plastic phase and a reactant phase is first densified at relatively low temperatures and then reacted at a higher temperature to produce a composite fully comprised of hard and refractory phases. In this paper, TPPP is employed to fabricate TiCx/TiB2/Ti3B4 composites starting from three different powder mixtures, 4:1 Ti/B4C, 1:0.5:1 Ti/C/TiB2 and 1:1 TiC0.5/TiB2, that are equivalent in terms of elemental composition. These composites were found to posses similar final phase composition, but distinctly different microstructures. Of particular importance is the platelet morphology of Ti3B4 in the composites produced from the 4:1 Ti/B4C starting composition. Preliminary results on ambient and elevated temperature mechanical properties of the fully dense composites for the studied compositions were reported The factors effecting the homogeneity of microstructure in these composites were also identified. These results combined with our previous work on microstructural evolution studies provide guidelines for further microstructural optimization.
