Utilizing The Master Sintering Curve to Probe Sintering Mechanisms

摘要

The master sintering curve (MSC) is empirically derived from densification data obtained over a range of heating rates or sintering temperatures. When the proper activation energy is used, all the data converge onto a single curve, the MSC. The activation energy can be estimated readily with just a few dilatometer experiments if it is unknown beforehand. Once established, the MSC makes it possible to predict the final density after arbitrary temperature-time excursions. It is particularly useful when considering alternative sintering methods. The MSC works if a single activation energy controls sintering, but also makes it possible to detect concurrent mechanisms.
