Q2. What is the effect of the SHS process on the synthesis of ceramic composites?
In addition, when ceramic composites are synthesized, it is observed that stronger interfacial bonds are established between the fine grains of the different phases simultaneously formed in-situ, which lead to a reduction of the diffusion distances [24].
Q3. What is the main reason for the interest in high-entropy ceramics?
The strong interest in these materials stems from the improved thermal stability and strengthening they usually exhibit with respect to conventional alloys [3-5]
Q4. What is the stoichiometric value of the reactants?
B2 (1)The use of a slight excess of B (x=0.2) with respect to the stoichiometric value allows for, in agreement to previous studies related to the obtainment of individual metal diborides [17-18], the removal of oxide impurities initially present in the raw powders.
Q5. What is the significance of the results discussed in this work?
On the basis of the results discussed in this work, it is possible to state the SHS method represents a suitable tool for obtaining powders to be processed by SPS for the fabrication of innovative high entropy ceramics.
Q6. What are the main aspects of the SHS process?
These aspects are also expected to play a beneficial role in promoting the atomic diffusion in SHS powders for the formation of the single phase HEBs during the SPS stage.
Q7. What is the way to describe the SHS process?
On the basis of the results discussed in this work, it is possible to state the SHS method represents a suitable tool for obtaining powders to be processed by SPS for the fabrication of innovative high entropy ceramics.
Q8. What is the potential of this HEB for industrial applications?
Of course, the potential of this HEB for industrial applications can be better defined when residual porosity of the bulk sample will be reduced, so that the mechanical properties and oxidation resistance could be correspondingly improved.
Q9. What is the potential of the HEB for industrial applications?
Of course, the potential of this HEB for industrial applications can be better defined when residual porosity of the bulk sample will be reduced, so that the mechanical properties and oxidation resistance could be correspondingly improved.
