Microstructural Parameters in the Theory of Critical Distances David Taylor Mechanical Engineering Department, Trinity College Dublin, Ireland dtaylor@tcd.ie Keywords: Critical distance; microstructure; fracture; grain size; damage zone Abstract.
Given that this conference is devoted to the relationships between material microstructure and fracture mechanisms, it is a useful forum at which to discuss the relationship between L and microstructural parameters.
A special issue of the journal Engineering Fracture Mechanics, containing 15 articles on this topic, is in preparation and will be published later in 2007.

Introduction In recent, several industries like manufacturing, and in engineering the enhancement of heat transfer performance is an essential topic.
Now a day, many researchers have been conducted their work on squeezing flows using the advanced numerical methods [17].

Although these most pure of clays have very low impurity contents, the carbothermal process tends to generate amorphous phases that eventually limit their application as advanced engineering materials.
Nevertheless, there is considerable scope for less demanding applications such as wear parts or advanced refractories, provided the process engineering and process economics can be managed.
Over a three year period this goal was successfully achieved, leading to the establishment of New Zealand’s first advanced ceramic industry, supplying advanced refractory products to export and domestic markets in the aluminium industry.
This has lead to commercialisation of sialon technologies, initially as advanced refractory ceramics, and more recently for wear parts and engineering applications.
