Melting point of group IV and V transition metal diborides
The environmental conical nozzle levitator system enables cooling trace experiments above 4000 K. These cooling trace experiments were used to determine the melting points through observation of thermal arrest of group IV and V transition metal diborides (TiB2, Tm = 3313 ± 33 K; ZrB2, Tm = 3404 ± 38 K; HfB2, Tm = 3529 ± 33 K; and TaB2, Tm = 3284 ± 10 K;

Abstract Agglomerations of carbon‐based inclusions and the low adhesion of inclusion‐matrix interfaces are commonly viewed as detrimental to the strength and fracture toughness of ceramic composites. While large, high‐power agglomerations indeed promote microcracking, our computations show that moderate agglomeration levels can enhance energy ...

Abstract Silicon carbide (SiC) is a promising material for hypersonic thermal protection systems, but its complex oxidation behavior—marked by transitions between passive, active, and interfacial bubbling regimes—can lead to catastrophic failure. Existing SiC models typically focus exclusively on either passive or active oxidation.
