Transmission electron microscopical study of the stainless steel specimens after ion-plasma treatment
The Effect of Personal Health on the Formation of Human Capital: a Metasystem Approach
In article the problem of influence of the personality's health on formation of the human capital is considered. Authors have conducted theoretical researches of the existing knowledge of the human capital and justifications of influence of the personality's health on its formation are given. On the basis of the carried-out analysis it is established that now the personality's health is a significant factor of efficiency of any kind of activity and important quality of the personality, therefore, it can be considered as a factor of formation of the human capital. According to it need of determination of criteria, the indicators of health of the personality influencing formation and development of the human capital was designated
Microstructural inhomogeneity of phase composition and grain structure in electron beam wire-feed additive manufactured AISI 304 stainless steel
A comparative study of the macroscopical and microscopical fracture mechanisms in cast and additively manufactured austenitic stainless steels
The effect of hydrogen on strain hardening and fracture mechanism of high-nitrogen austenitic steel
High-nitrogen austenitic steels are perspective materials for an electron-beam welding and for producing of wear-resistant coatings, which can be used for application in aggressive atmospheres. The tensile behavior and fracture mechanism of high-nitrogen austenitic steel Fe-20Cr-22Mn-1.5V-0.2C-0.6N (in wt.%) after electrochemical hydrogen charging for 2, 10 and 40 hours have been investigated. Hydrogenation of steel provides a loss of yield strength, uniform elongation and tensile strength. The degradation of tensile properties becomes stronger with increase in charging duration - it occurs more intensive in specimens hydrogenated for 40 hours as compared to ones charged for 2-10 hours. Fracture analysis reveals a hydrogen-induced formation of brittle surface layers up to 6 [mu]m thick after 40 hours of saturation. Hydrogenation changes fracture mode of steel from mixed intergranular-transgranular to mainly transgranular one
