Journal ArticleDOI
Effect of heat input on phase content, crystalline lattice parameter, and residual strain in wire-feed electron beam additive manufactured 304 stainless steel
Sergei Yu. Tarasov,Andrey V. Filippov,N. L. Savchenko,S. V. Fortuna,Valery E. Rubtsov,E. A. Kolubaev,Sergey G. Psakhie +6 more
TL;DR: In this article, structural and mechanical characterization of electron beam additive manufactured stainless steel samples has been carried out, where the XRD measured austenite and ferrite lattice parameters showed their sensitivity to the heat input value, which was related to the chromium atom redistribution.
Journal ArticleDOI
The effect of wire feed geometry on electron beam freeform 3D printing of complex-shaped samples from Ti-6Al-4V alloy
K. N. Kalashnikov,Valery E. Rubtsov,N. L. Savchenko,Tatiana Kalashnikova,Kseniya Osipovich,A. A. Eliseev,Andrey Chumaevskii +6 more
TL;DR: In this article, two different ways of obtaining complex-shaped bell-type samples from the titanium alloy Ti-6Al-4V were studied and the structure of geometry affected zones was determined and the most optimal way for obtaining the samples was selected.
Journal ArticleDOI
Controlling the porosity using exponential decay heat input regimes during electron beam wire-feed additive manufacturing of Al-Mg alloy
V. R. Utyaganova,Andrey V. Filippov,N. N. Shamarin,A. V. Vorontsov,N. L. Savchenko,S. V. Fortuna,D. A. Gurianov,Andrey Chumaevskii,Valeriy E. Rubtsov,S. Yu. Tarasov +9 more
TL;DR: In this paper, an optimal heat input gradient was determined which allowed growing a defect-free metal in the bottom part of the sample and forcing out the shrinkage cavities to the top part.
Journal ArticleDOI
Adaptation and self-healing effect of tribo-oxidizing in high-speed sliding friction on ZrB2-SiС ceramic composite
N. L. Savchenko,Yu. A. Mirovoy,A. S. Buyakov,A. G. Burlachenko,Maxim Rudmin,I. N. Sevostyanova,S. P. Buyakova,S. P. Buyakova,S. Yu. Tarasov +8 more
TL;DR: In this article, the adaptive mechanisms and behavior of ZrB2-20-vol% SiC ultra high-temperature ceramics in low-speed and high-speed sliding against a high-carbon steel disk were investigated.
Journal ArticleDOI
Deformation and Fracture of Porous Brittle Materials Under Different Loading Schemes
N. L. Savchenko,T. Yu. Sablina,I. N. Sevostyanova,S. P. Buуakova,S. P. Buуakova,S. N. Kul'kov,S. N. Kul'kov +6 more
TL;DR: The behavior of alumina and zirconia compression-and shear-test specimens with porosity ranging from 10 to 70% was investigated in this paper, which revealed a transition from a characteristically brittle fracture of fairly dense Al2O3 and ZrO2 specimens to pseudo-plastic fracture for a high porosity level.
