The structural change and properties of W6Mo5Cr4V2 alloy (M2 steel) inoculated by addition of rare earth (RE)-Ti were investigated.
Many attempts have been made to develop a process to minimize carbide segregation and increase the properties of M2 steel [6,7].
However, the studies are very limited about the effects of modification on the M2 steel properties, especially high temperature wears resistance and thermal fatigue resistance.
In this paper, the effect of RE-Ti composite modification on the structure and properties of M2 steel was studied.
This is because the morphology of carbides is the main factor affecting the properties of iron and steel.

Introduction Silicon nitride is an advanced ceramic material with attractive mechanical, thermal, chemical, electrical and optical properties [1,2].
On the other hand, nucleation and growth of phases obtained by CVD are determined by two major factors: the concentration (supersaturation) of adsorbed monomers or atoms on the surface, and the temperature which relates to their mobility.
The type of nitrogen precursor affects not only the morphology but also the amount of the products.
The type of nitrogen precursor affects both dissociation of the solid precursor (Na2SiF6) and formation of Si3N4.

., the possibility of measuring the elastic modulus as a function of the processes proceeding in a specimen and affecting the structure of a polymeric material (aging, sorption, and desorption of liquid media and vapors by the material, temperature variations, etc.).
The initial information for development of the plan is the number of factors n and the number of experiments k.
The points of experiments in the domain of factors are distributed as regularly as possible (Fig. 2).
The elastic properties of the material were modeled by Hooke’s relations.
The method allows one to use the "principle of a unified specimen", i.e., the possibility of measuring the elastic modulus as a function of various processes affecting the structure and properties of a polymeric material (aging, action of temperature and moisture, etc.).

There exist many factors affecting the hardness and optical properties of the coatings.
Authors of ref. [8] established a correlation between the Raman data and the structural properties of the films.
However, this correlation may appear incomplete because the film growth process is generally affected by many factors related to the substrate properties, and this influence may have an impact on the coating structure.
Different structural factors can be responsible for hard coatings.
