Creep of Reaction Sintered and Liquid Phase Sintered Sialon

Journal of the Mechanical Behavior of Materials, 1990
Creep experiments were conducted with 100—250 MPa stress at 1200-1450°C of Reaction Sintered (RS) Sialon A synthesized from Si3N4-AlN-Al203 and Liquid Phase Sintered (LPS) Sialon C, CI synthesized from Y203-A1N-Si02 systems. RS Sialon A, containing no liquid phase sintering aid, had better creep resistance than LPS Sialon C, CI.

Master Sintering Surface: A practical approach to its construction and utilization for Spark Plasma Sintering prediction [PDF]

, 2012
The sintering is a complex thermally activated process, thus any prediction of sintering behaviour is very welcome not only for industrial purposes. Presented paper shows the possibility of densification prediction based on concept of Master Sintering

Influence of pulse current during Spark Plasma Sintering evidenced on reactive alumina–hematite powders [PDF]

, 2011
Spark Plasma Sintering (SPS) is increasingly used. The temperature and current are not independent parameters, making it difficult to separate the current intrinsic role from Joule heating.
