Molecular dynamics simulation of the tensile response and deformation mechanism of diamond/TiC combinations

Probing the Atomic Erosion Wear Characteristics of TiC-Coated Fe in Oil and Gas Drilling Environments

“…11,12 In the study of the fracture mechanism and deformation behavior of diamond and TiC(001), (110), and (111) single crystal coating combinations under uniaxial tension, the preferential conclusion of TiC{111} partial dislocation nucleation and slip was demonstrated. 13 At the same time, the study found that in TiC(111) single crystal coatings with special lattice structures, the Ti interface had higher adsorption energy and lower interface energy. 14 Although these studies and conclusions provide important reference significance for the application of TiC coating materials in practical engineering fields, the vast majority of research on TiC coating materials remains at the level of using macroscopic theoretical and experimental methods to characterize their working mechanisms.…”

“…The presence of the TiC phase in composite materials will enhance the material’s interfacial bonding strength, hardness, and oxidation resistance, thereby improving the erosion and abrasion resistance characteristics of the composite material . Additionally, TiC-phase particles with shallow distribution depth and large radius can hinder the formation and development of defects, reducing the degree of subsurface damage in composite materials. , In the study of the fracture mechanism and deformation behavior of diamond and TiC(001), (110), and (111) single crystal coating combinations under uniaxial tension, the preferential conclusion of TiC{111} partial dislocation nucleation and slip was demonstrated .

Microstructural evolution and mechanical characterization for the AlCoCrFeNi2.1 eutectic high‐entropy alloy under different temperatures

“…The AlCoCrFeNi 2.1 eutectic HEAs (EHEAs) contain conventional FCC and BCC layered structures. Due to the back stress created when the two phases meet during tensile deformation, it offers an excellent mix of high strength and ductility 9,10 . Weak castability, liquidity, and composition inhomogeneity typically limit large‐scale manufacturing of HEAs through casting.…”
