“…A C C E P T E D ACCEPTED MANUSCRIPT 4 sometimes referred to the spark plasma sintering, SPS) has been employed successfully to join Zr-alloy cladding tubes [16], ZrB 2 -SiC composites [17], MAX phase [18], and SiC and C/SiC composites within a 3 -10 minutes holding time [19]. S. Grasso et al [20] successfully joined β-SiC with or without Ti foil by SPS.…”

“…An alternative method is to measure the temperature closer to the specimen surface through the loading train [33]. As the actual sintering temperature(s) within the specimen can be dramatically different than what is readily witnessed on the die surface or even closer to the specimen surface, the simulation results of most interest from a process control viewpoint are the horizontal temperature gradient that develops between the die surface and the center of the compact and the gradient within the compact itself.…”

A fully coupled thermal-electric-sintering finite element model was developed and implemented to predict heterogeneous densification in net-shape compacts using electric field assisted sintering techniques (FAST). FAST is a single-step processing operation for producing bulk materials from powders, in which the powder is heated by the application of electric current under pressure. Previous modeling efforts on FAST have mostly considered the thermal-electric aspect of the problem and have largely neglected the sintering aspect of the problem. A new model was developed by integrating a phenomenological sintering model into a previously established thermal-electric finite element framework to predict the densification kinetics of the sample. The model was used to quantify the effect of specimen geometry on the evolution of thermoelectric gradients and resulting heterogeneous sintering kinetics during FAST processing of a conductive powder. It is shown that the new model which considers sintering kinetics and density-dependent properties provides a substantial increase in accuracy compared to thermal-electric only models. It is also shown that small changes in local resistance due to densification can greatly impact the distribution of thermoelectric gradients during the process, which are exacerbated by heterogeneous stress states induced by sample geometry. Experimental characterization of sintered specimens is used to provide qualitative validation of the model predictions.

“…Liu et al shows how SPS can be utilized for joining dissimilar (nanocrystaline) sintered materials such as Ni 3 Al and TiC/Ni 3 Al [139]. SPS has shown to be an effective approach for joining of CVD-SiC coated C/SiC composites, directly and with glass-ceramic (CA), a SiC + 5 wt% B 4 C mixture and pure Ti foils as joining materials [198]. Furthermore have SPS been used for Ti to Steel joining, without the brittle Fe-Ti intermetallic compounds (IMC) and shape distortion of parent materials [157].…”
