| Abstract Scope |
A fundamental understanding on the microstructural evolution during sintering is key to tailor the properties of ceramics for applications such as structural, energy storage, and electronic devices. Historically, the connection between the spatially resolved microstructural evolution and the resultant macroscopic densification of a ceramic solid during sintering has been described in terms of two-particle models. However, randomly packed granular structures into green bodies results in a complex network of stresses and regimes of sintering that challenges the classic description. In this presentation, a phase-field formulation was developed to establish a formal relationship between mechanical, spatially complex mesoscale and the macroscopic engineering level, enabling a multi scale understanding of the effect of microstructural evolution during densification and its impact at the macroscopic scale. Short and long time scales as a function of applied stress, porosity, and particle morphology are quantified as a stepping stone to have a holistic understanding of sintering. |
