“…Figure 9 summarizes the H V and K IC of CrB 2 ‐based binary and ternary composites in literature and the present study. The H V and K IC of all the pure CrB 2 were less than 22 GPa and 3.8 MPa m 1/2 , respectively 3,11,35 . Most of the CrB 2 ‐based composites were prepared by HP, which has the advantages of relatively low sintering temperature and good sintering quality.…”

“…Hence, the crack propagation is not easy at the eutectic interface. The propagation of the indentation crack at the eutectic composition was predominantly transgranular mode (Figure 8C 3,7,11,[35][36][37][38] extended in mixed transgranular and intergranular modes (Figure 8A,B). Branching and bridging, which consume energy of crack propagation, prevent the crack from expanding, as toughening mechanisms were also found in the microstructure.…”

B 4 C-CrB 2 composites were prepared by arc-melting using B 4 C and CrB 2 powders as raw materials. The eutectic composition of B 4 C-CrB 2 system was 30B 4 C-70CrB 2 (mol%) with a labyrinth-like irregularly layered eutectic microstructure, composed of B 4 C phase about 1-2 μm in thickness dispersing in CrB 2 matrix, much smaller than raw powders. The interface of the eutectic composite was well bonded, and there were edge dislocations at the interface to alleviate the interface mismatch. The eutectic temperature of B 4 C-CrB 2 composites was approximately 2200 K. At the eutectic composition, the B 4 C-CrB 2 composites showed the maximum Vickers hardness (24.6 GPa) and fracture toughness (4.3 MPa m 1/2 ) at room temperature.

According to the estimates of many authors, in 10-15 years, the world market for nanotechnology products will amount to about 1 trillion $. The share of nanomaterials, in this case, is very large (about 340 billion). Therefore, research on nanomaterials properties becomes one of the most important tasks of the science of nanostructured materials. In this regard, it will be essential to expand research on the influence of size and thermal stability; as two common problems for almost all types of nanomaterials. This review article will discuss the most popular topics on nanomaterials, nanostructures, their history, characteristics and classification as well as status of their scientific articles published in recent years. This study focuses on a range of topics related to the development, research and manufacturing applications of nanomaterials and nanotechnology. There are many problems and challenges that scientists are investigating on them. For example: what are the main differences between the properties of interfaces of nanomaterials (including hybrid ones) from the characteristics of ordinary bulk states? How widely can the self-assembly technique of nanoscale devices elements be developed, considering possible installation errors?
