This paper provides a thorough review on high-pressure spark plasma sintering (HP-SPS) experiments conducted to date, with focus different tooling materials and their impact microstructural, mechanical optical properties of the resulting materials. Any SPS experiment pressure over 200 MPa was considered as "high-pressure". supported by comprehensive finite-element modelling study temperature distribution in sample tool set-up function used geometries, material combinations, window...
High-entropy ceramics is a new class of materials having great potential and wide application. The carbide Ti, Zr, Hf, Ta, Nb typical member this group. It has been synthesized mostly through blending, milling, high-temperature solid-state reaction metal precursors for each metal. This route needs extremely high temperature (2300 °C), which makes it energy technology demanding. We have developed chemical high-entropy powder that synthetic several hundred degrees Celsius lower. A solution...
Abstract Iodine release modelling of nuclear fuel pellets has major uncertainties that restrict applications in current performance codes. The origin from both the chemical behaviour iodine pellet and different species. structure evolves due to neutron fission product irradiation, thermo-mechanical loads interactions. This causes extra challenges for modelling. After sufficient amount a new type starts forming at cylindrical outer edge. porous is called high-burnup or rim structure. effects...
