“…Considering the case of conducting pores, 01' more generally the case of two-phase materials, one has to return to the general equations of Niesel 16,19,20,25). One of them is valid for matrix-structured material corresponding to closed, isolateel pores.…”

A. Typical BehaviorIn this discussion, the concern is with the properties of systems with high volume fractions of solid (typically over 50"o solid at the sintering temperature), which includes most practical materials processed by liquid phase sintering techniques. There is a diversity of final mrcrostructures possible by liquid phase sintering. The microstructure carries over to affect the properties, especially mechanical behavior. However, microstructure is not the only factor affecting the properties of !iquid phase sintered materials ( 1, 2). Table 9. 1 lists the specific factors by categories of powder characteristics, sintering cycle, alloy composition, post-srntering heat treatment, sintered microstructure, and testing conditions. In light of such diversity, it is difficu It to rna ke specific statements about optimal conditions. However, there are some general results which provide insight to the links between composition, processing, microstructure, and properties.

“…[21][22][23] The measurements outlined below were therefore carried out primarily to ascertain the influence of the inner porosity of the U0 2 particles on properties. All the measurements were carried out on extruded samples of a high matrix density (99,7% TD) after rem oval of the cladding material.…”
