Abstract
Certain material deformation properties of a typical alumina based ceramic paste system, including the hardness (a plastic yield characteristic), the elastic modulus, a plasticity index (a measure of the relative elastic-plastic response), and a mean flow stress, are obtained using an indentation hardness test. In order to compute these material properties a contact compliance procedure, in conjunction with an analysis based upon an adaptation of the Box-Cox curve fitting method for the compliance curve, has been used The data are used to provide a basis for identifying the optimum rheological response of the paste system for plastic forming operations.
