Processing and Application of Ceramics, 2022 Ceramic composites consisting of a boron carbide (B4C) matrix and titanium diboride (TiB2) secondary phase were obtained by reactive sintering from boron carbide powder with 40 and 50wt.% of titanium dioxide (TiO2) additive. The same sintering temperature of 1850?C and pressure of 35MPa, but different sintering times from 15 to 60min, were ...

Materials Genome Engineering Advances, EarlyView.Cu/diamond heat spreaders are limited by low thermal boundary conductance. Using DFT + DMM, we identify the phonon‐transport factors governing TBC and show that optical–phonon contributions and branch conversion are essential. High‐k $k$ carbides (B4C, WC) and residual B and Cr improve interfacial heat transfer, enabling robust performance versus ...
