Objective
Despite their incredible durability, ceramics used are hampered by two limitations: they are difficult to manufacture compared with continuous manufacturing of metals and polymers, and they are brittle, even at relatively high temperature. Both these limitations are coming from their low fracture toughness and the absence of plastic deformation mechanisms. One the goal of my ERC SSTEEL was to find a way to toughen ceramic composites by introducing strain hardening mechanisms at the nanometric scale. We succeeded and produced a ceramic composite that show plastic deformation of at least 14% and toughness two orders of magnitude higher, in terms of energy release rate, than conventional structural ceramics at temperature around 1000°C. These temperatures are close to the ones used to hot forge steel and thus open two new applications avenues for these deformable ceramics. One is enabling ceramics forging, using preform to produce complex shapes in a quick and simple way. The other is using this high toughness to produce structural ceramics for high temperature applications, in burners or even engines. The goal of this Proof-of-Concept project is three-fold: 1. to work on the ceramic composition to lower the temperature needed for deformation or improve their high temperature mechanical resistance, 2. to develop the forging of ceramic beyond the initial results to showcase the capabilities to future clients, 3. to start testing the continuous processing of these composites. Succeeding in these goals holds promises for cheaper and faster manufacturing of complex-shaped ceramic parts, opening a wealth of potential applications previously limited to metals or polymers, as well as developing more ductile high temperature stru
