“…Zr–Si intermetallic compounds have been widely applied in various fields including thin films, refractory components, diffusion barriers, ceramics, and biomedical materials with their favorable properties . Zr 2 Si and Zr 5 Si 3 are considered as the reinforcing phase forming in Zr‐based alloys and Ti‐based alloys, respectively, which is important to improve the mechanical properties of lightweight refractory alloys .…”

A first-principles investigation on the electronic structure, mechanical, and thermal properties of Zr-Si compounds has been investigated to prompt the development of new materials. The influence of Si content on mechanical and thermal properties is clarified. All the Zr-Si compounds are strikingly incompressible under uniaxial stress along x, y, and z axes. β-ZrSi possesses the strongest resistance to shape change and uniaxial tensions. α-ZrSi presents better performance of the resistance to volume change. The bulk modulus first increases and then decreases with the increase of the Si concentration. All the compounds exhibit brittle behavior. These zirconium silicides have relatively low bulk and shear modulus, but the shear anisotropy is strongly dependent on diverse directions. Debye temperature increases linearly with the increase of Si content. ZrSi 2 shows the best capacity of thermal conductivity. The minimum thermal conductivity in all the crystallographic directions is progressively increased with the increase of Si content except for β-ZrSi in the [010] direction.

Intermetallic compounds with special physical and chemical properties are considered to be advanced materials. However, the brittleness at room temperature of intermetallic compounds leads to poor performance, which limits its widespread application in engineering. The objective of this study is to investigate the strengthening mechanism of the copper (Cu) on the microstructure and material performance of WC/NiAl/TiC composite coatings by the laser cladding process. The results reveale that Cu element has a significant effect on the microstructure evolution of the coatings by inhibiting coarse crystal formation. The refined microstructure of the layer had been realized. X‐ray diffraction (XRD) analysis demonstrate a reduction in lattice spacing within the composite coating structure as the proper Cu is added. Furthermore, the addition of Cu contributed to an enhancement in microhardness (868.9 HV0.2) and wear resistance. With 3% copper been added, the wear loss of the coatings has been reduced by 81.13% and the average microhardness value has been increased by 1.4 times as well. Moreover, the chemical metallurgical bond is produced between the particles and bonding phase resulting in strengthened compactness within the layer acting as a physical barrier‐like film that increases polarization resistance.
