Fracture toughness and thermal shock of tool and turbine ceramics
The behaviour of some commercial tool carbides and turbine ceramics has been investigated in regard to resistance to crack initiation, crack propagation and retained strength after thermal shock. New data are provided, particularly measurements of the fracture toughness of these materials at actual operating temperatures (up to 1200 ~ C). Many of the materials did not follow the generally accep...
متن کاملInfrared Thermopile Temperature Measurement Technique in Microwave Heating Systems
Temperature measurement in microwave systems is essential for thermally driven processes, namely, catalytic reactions and ceramic sintering. Although, the application of direct thermometry methods, namely, thermocouples, have been commonly articulated in the available literature, however, contacted temperature measurement mechanisms have aroused concerns associated with the disruption of the el...
متن کاملThermal-stress resistance and fracture toughness of two tool ceramics
The thermal-stress resistance and fracture strength behaviour of two oxide ceramics (a hot-pressed pure AI203 and a composite ceramic NTK-HC2) subjected to severe thermal shocks have been investigated. The damage resistance parameter (Kic/of)2 for both ceramics is also determined for a wide range of temperatures (25 ~ to 800 ~ C) and cross-head rates (10 -2 cm min -1 ~ 2.5 m sec -1 ). Fracture ...
متن کاملThermal Stress Resistance to Fracture and its Relation to with Resistance to Thermal Fatigue and Shock
Dense Silicon nitride was investigated to determine the effect of its microstructural parameters and densification on thermo-mechanical properties and thermal stress resistance to fracture initiation during a hot or cold mechanical and thermal shock testing. The different materials and microstructures were obtained by changing the parameters such as the type of the powder, additive, forming p...
