Modelling WC-Co sintering shrinkage - Effect of carbide grain size and cobalt content
2007 (English)In: Materials Science & Engineering: A, ISSN 0921-5093, Vol. 452, 37-45 p.Article in journal (Refereed) Published
Phenomenological models based on the constitutive parameters uniaxial viscosity, viscous equivalent of Poisson's ratio and sintering stress are used to describe WC-Co sintering shrinkage. Shrinkage is divided into three subsequent stages. The influences of carbide grain size and cobalt content are accounted for and model parameters numerically adjusted to dilatometer results. The model successfully represents published shrinkage data for different materials and milling procedures.
