Transformation and R-curve behaviour have been investigated in 9 mol% Ce-TZP ceramics with different grain sizes. Both single-edge notched beam and short double-cantilever beam specimens were tested to measure the crack-resistance curves. The size an

The effect of particulate TiN additions (0–50 wt%) on creep behaviour of hot-pressed (5 wt%Y2O3 + 2 wt%Al2O3)-doped silicon nitride (HPSN)-based ceramics was studied. Creep was measured using a four-point bending fixture in air at 1100–1340 °C.

High Temperature Resistant Silicon-Nitride Ceramics by Optimized Two-Step Gas Pressure Sintering

Autor: G. Grathwohl, R. Oberacker

Publikováno v: Tailoring of Mechanical Properties of Si3N4 Ceramics ISBN: 9789401044301

The potential of two-step gas pressure sintering as a production method for high-temperature resistant silicon nitride ceramics was evaluated. In a first step, a strategy for process optimization was derived from a comprehensive investigation on proc

The progress in the development of advanced structural ceramics is characterized by a remarkable increase in their strength and fracture toughness. Further improvement of these essential mechanical properties is still desirable and requires a fundame
