Dynamic Elastic Determination of the Properties of Sintered Powder Metals

  • Chapter
Advanced Experimental Techniques in Powder Metallurgy

Part of the book series: Perspectives in Powder Metallurgy ((PEPOME,volume 66))

Abstract

Powder metallurgy products normally contain an inherent amount of residual porosity which gives the product reduced density. Sintered density is a commonly specified characteristic of powder metallurgy products, because, to a first approximation, mechanical properties are related to density. Often, however, this is a poor approximation due to the recognized fact that porosity, per se, does not determine the properties of the product; that is, at any level of density, properties may vary over a relatively wide range. The size, shape and distribution of the porosity, in addition to interparticle bonding also contribute to the mechanical properties1,2,3. These factors are controlled by a multiplicity of processing variables that are difficult for the user to specify or monitor.
