Документ Закономірності формування структурних та механічних властивостей сплава системи Zr-Nb в умовах інтенсивних пластичних деформацій(НТУ "ХПІ", 2013) Злочевська, Н. К.The regularities of formation of the structural properties were determined by deformation in isothermal conditions. The relationship between deformation intensity, structure of material and his mechanical properties was established on the base of experimental forming by the method of helical forging of workpieces, on the base of finite element modeling and metallographic investigation. It was grounded that the plasticity increases at the cost of the refinement of structure components of material.Документ Влияние трения на напряженно-деформированное состояние кольца при холодной раскатке(НТУ "ХПИ", 2013) Симсон, Эдуард Альфредович; Scicluna, Steven; Хавин, Валерий Львович; Автономова, Людмила ВладимировнаIt is considered the problem of numerical modeling of cold rolling bearing rings. The resolved equations of mathematical formulation is provided. In the three-dimensional formulation contact problem is solved numerically for different coefficients of friction by using a finite element software DEFORM.Документ Выглаживание деталей из титановых сплавов с использованием металлосодержащей смазки(НТУ "ХПИ", 2013) Лавриненков, А. Д.The article presents the results of the use of metal-containing lubricants in burnishing process with application of an ultrasound of details made of titanium alloy VT22 and VT23. It was found that their use expands the technological capabilities of the process by controlling the speed and processing effort, and also provides quality parameters of the surface layer.Документ Вплив температури на характер пластичної деформації високомідистих чавунів(НТУ "ХПІ", 2013) Гусачук, Д. А.; Савчук, П. П.; Фещук, Ю. П.; Мельничук, М. Д.This paper investigated the characteristics of plastic deformation high-cooper cast iron at elevated temperatures. Found that the presence high-cooper phase can increase the plasticity alloys. The presence of a thickened shell of high-cooper phase around the primary crystals of graphite enables avoid the phenomenon of graphite foliation, which is characteristic of ordinary cast iron. Deformation at temperatures close to 700°C, the effect of subcritical superplastic alloys developed.
