Abstract
Transient Plastic Phase Processing (TPPP) is a new technique capable of in‐situ manufacturing complex shaped, fully dense, ultra‐refractory ceramic‐ceramic composites at temperatures that are significantly lower than their melting points (T < 0.65 T
m
). In TPPP two phases in particulate form are mixed, of which one is a transient plastic phase (TPP) and the other is a reactant phase (RP). In essence, TPPP includes: (i) plastic forming at a relatively low temperature in a soft condition resulting in densification of the powder mix with no change in the composition of the constituents, followed by (ii) reaction synthesis at a higher temperature in which the RP reacts with the TPP and shifts its stoichiometry to a harder, more refractory composition. The feasibility of this technique has been demonstrated on the Ti‐B‐C system. Experimental observations of the effect of the starting compositions on the final microstructures, porosity, and the mechanical properties of produced composites are discussed.
