This paper presents experimental data and its interpretation regarding the forming of YAG spinel green-bodies, intended for transparent parts fabrication, by pressure slip casting (PSC) method. Conditions an optimal operation are established based on modeling filtration kinetics. It emerges that method is able to provide highly sinterable green ensuring cakes porosity exhibits low average size ...

Abstract The influence of different initiation manners on the forming features reactive material jets was investigated using AUTODYN-3D simulation software. numerical findings demonstrate that, as compared to center point initiation, annular multi-point greatly improves velocity jet head created, but expansion impact is more noticeable during generating process. At and axis jet, there are low d...

Over the last years, the demand for high strength and low weight materials, such as fabric-reinforced plastics, has grown in the aeronautical industry. By decreasing the production cost with short production cycle times and increasing reproducibility by automation, fabric-reinforced plastics are becoming increasingly better economical competitors to other construction materials such as for exam...

Compaction of Bi and Ta powders was performed by uniaxial pressing at room temperature. Post-pressing density was evaluated as a function of the compaction pressure, and indicated that as the Ta content increases there is a reduction in density for comparable pressing conditions. A modified Heckel equation is used to evaluate the compaction behavior. The analysis indicates that the yield pressu...

The hippocampal EEG activity was recorded in male rats during the response-contingent reinforcement of a female. The instrumental response was a bar-pressing on a fixed-ratio-10 reinforcement schedule. The frequency of bar-pressing tends to increase during the succeeding copulatory series. The similar phenomenon was observed in the frequency of the hippocampal slow activity (RSA) accompanying t...
