Summary

Two-phase (α′ + β′) SiAION composite materials have been prepared using self-reinforcing and transient-liquid-phase techniques. The one-step process produces a glass-free material with an intimate mixture of elongated β grains and fine equiaxed α grains that has excellent room-temperature mechanical properties and retains them with thermal stability at temperatures as high as 1400°C.
