Skorohod-Olevsky viscous sintering model sensitivity to temperature distribution during the sintering process

چکیده
This paper investigates the influence of temperature field non-uniformity on sintering simulation results using Skorohod-Olevsky viscous model. As a difference to previous studies, here thermal transient analysis is performed provide detailed over component within time. Results obtained uniform distribution are compared those nonuniform derived from analysis. for different geometry sizes, that lead levels. The study has shown nonuniformity cannot always be neglected and should considered as possible source modeling error.

Sintering of viscous droplets under surface tension
We conduct experiments to investigate the sintering of high-viscosity liquid droplets. Free-standing cylinders of spherical glass beads are heated above their glass transition temperature, causing them to densify under surface tension. We determine the evolving volume of the bead pack at high spatial and temporal resolution. We use these data to test a range of existing models. We extend the mo...
متن کاملUltra High Temperature Microwave Sintering – Furnace and Process Design
Scale up of microwave sintering for high temperature stable non-oxide ceramics, such as SiC, Si3N4, and dispersion ceramics, like SiC-MoSi2 is still difficult, mainly because of lack of an affordable equipment. For air atmosphere sintering different furnaces were developed, like e.g., gas-microwave hybrid heated tunnel kilns [1] or microwave sintering using an adiabatic casket in tunnel kilns [...

متن کاملLow Temperature Sintering Additives for Silicon Nitride
This work deals with sintering additives for the low temperature pressureless sintering of Si3N4, via a transient liquid technique. Much attention has been given to the development of a sintering process using low-cost Si3N4 powder (Silzot HQ, Germany) as the starting material and employing sintering additives which are also both economically attractive and enable sintering at low temperatures....
متن کاملVolcanic sintering: Timescales of viscous densification and strength recovery
[1] Sintering and densification are ubiquitous processes influencing the emplacement of both effusive and explosive products of volcanic eruptions. Here we sinter ash-size fragments of a synthetic National Institute of Standards and Technology viscosity standard glass at temperatures at which the resultant melt has a viscosity of ∼108-109 Pa.s at 1bar to assess sintering dynamics under near-sur...
