ABSTRACTTo examine the effect of thermal expansion mismatch on cracking in two-phase Cr-Cr2X (X=Hf, Nb, Ta, Zr) alloys, we calculate the elastic constants and associated elastic anharmonicity by the local-density-functional approach from which the coefficients of thermal expansion (CTEs) of Cr and Cr2X are determined. The calculation shows that the CTE

2D nanomaterials have been reported to demonstrate interesting magnetic phases when doped with transition metal double impurities. To understand the atomistic origin of such magnetism in pristine, vacancy defected and cobalt (Co)-transition metal (V, Nb,

The non-isothermal oxidation behaviour of (Hf-Ta-Zr-Nb)C high entropy carbide (HEC4), component monocarbides (HfC, TaC, NbC, and ZrC), and (Hf-Ta)C binary carbide powders was compared and studied from room temperature to 1300°C using thermogravimetric ...

Compositional disorder and sintering of entropy stabilized (Hf,Nb,Ta,Ti,Zr)B2 solid solution powders
, 2020Entropy-stabilized (Hf,Nb,Ta,Ti,Zr)B2 solid solution powders produced by a carbo/boro-thermal reduction followed by solid solution formation were first analysed by synchrotron radiation x-ray diffraction, and their long range periodicity (i.e.

Flexural strength of (Hf,Nb,Ta,Ti,Zr)B2–(Hf,Nb,Ta,Ti,Zr)C high‐entropy dual‐phase ceramics
Journal of The American Ceramic SocietyThe room and elevated temperature flexural strengths were measured for (Hf,Nb,Ta,Ti,Zr)B2–(Hf,Nb,Ta,Ti,Zr)C high‐entropy dual‐phase ceramics. The fracture of ceramics originated from two distinct flaw populations that were either surface defects ...
