General Materials Processing Notes

The authors indicate that the work included evaluation of eight transformation-toughened ceramics, six silicon carbide ceramis, and twelve silicon nitride ceramics, all of which were commercial materials.

Measurement Methods

Vickers indentation
"Hardness was measured by a Vickers microindent hardness tester (Zwick 3213)". No additional measurement details were noted.
Toughness test
"Fracture toughness was measured by controlled flaw and microindent methods." No additional measurement details were noted.
Strength test
"Flexural strength - MIL-STD-1942(MR), specimen size B (ASTM C1161); 3 mm x 4 mm x 50 mm in four-point loading at 20 °C to 1400 °C was used. Dynamic fatigue behavior was evaluated by using crosshead loading speeds of 4x10-3 cm/s to 10-5 cm/s. Flexural stress rupture was evaluated at 1300 °C to 1400 °C for 100 h. Tensile strength - Testing was performed on an Instron electromechanical test system 1361 with Instron Super-Grip couplings, water-cooled grips, and a high-temperature short furnace. Sixteen and one half centimeter long buttonhead test specimens were used. Tensile strength was measured at several loading speeds (4x10-3 cm/s to 10-5 cm/s), in tensile stress rupture (up to 100 h), and in cyclic fatigue (R = 0.1)."
Dilatometry
"Thermal expansion was measured from 25 °C to 1400 °C using a Theta Industries Dilatronic II (Model 6024)." No additional measurement details were noted.
Ultrasonic method
"Elastic modulus was measured by a Grindo-Sonic (Model MR3ST) transient impulse/Elastic modulus apparatus (from 20 °C to 1400 °C)." No additional measurement details were noted.
