Abstract
Interface structures are a key feature in developing
modern composite material solutions with ever improved
performance. We present a nano-microstructural modelling
approach for the tungsten carbide (WC)-Co system which
can include the interface structures of WC-Co and various
other phases present in the microstructure, utilising a
methodology which combines imaging-based and
synthetically generated nano-microstructures into an
effective interface model for predicting the behaviour
and properties of the resulting composite material. The
effective model comprises of a local model of the WC/Co
interface interacting with a larger-scale model of the
WC-Co microstructure. The results provide a linkage
between the interface character of cemented carbide
microstructures and their properties, for example with
respect to compressive strength, fracture toughness and
wear resistance. The methodology presents a multiscale
formalism for carrying out performance and
application-driven evaluation and tailoring of composite
interfaces and mesostructures, carried out on the basis
of the emerging engineering material properties.
