Vibrational Properties of Zr(Hf)B2–SiC UHTC Composites by Micro-Raman Spectroscopy

2D Raman mapping and thermal residual stresses in SiC grains of ZrB2–SiC ceramic composites

“…3D, H, L, and P, which show a matching trend with similar results published in Ref. [25]. From the comparison of both experimental and theoretical results, there is a rather good correspondence, and the values of piezospectoscopy coefficients are rather close to each other.…”

“…This paper will present the results of measurements and calculations of surface residual stresses in ZrB 2 -SiC particulate ceramic composites, which is an important material for ultra-high temperature applications [21][22][23][24][25][26] using 2D Raman mapping.…”

In situthree point bending device for measurements of vibrational response of ceramics under stress by microRaman spectroscopy

“…While it was found that ZrB 2 phase exhibits two Raman active peaks,27 the intensities of the peaks are not very high. It is well known that SiC Raman active bands are stress sensitive and can be used to study the appearance of stresses in SiC phase 28.…”

Guideline of mapping parameters for Raman mapping of ZrB2–SiC ceramic composites

“…Fully dense ZrB 2 -10 wt-%SiC ceramic composites were used for measurements. 22,[31][32][33] The samples were produced by weighting the ZrB 2 powder (H.C. Starck ZrB 2 grade B) and the SiC powder (H.C. Starck a-SiC grade UF-10) and then grinding them together, followed by sieving the powers to break up the agglomerates. The composite was processed by spark plasma sintering at 1950uC and 50 MPa for 15 min with a heating rate of 100uC min 21 .…”
