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.Документ Взаємодія технологічних параметрів в осередку деформації при сталому процесі прокатування(НТУ "ХПІ", 2013) Бережний, М. М.; Чубенко, В. А.; Хіноцька, А. А.; Шепель, А.; Чубенко, В.The center of the strain was at the established process of rolling was considered, deforming voltage and resistance force viscosity flow in the deformation were compared and the mean values of the borders of fluidity at a different modes rolling, calculated rate of strain in compression, widing and lengthening.was calculated. It was determined that the increase in the strain velocity in broadening and elongation leads to increased border flow, which causes the necessity to increase the speed of rolling, which in turn helps to increase the productivity of the process.Документ Влияние температуры и скорости деформации на механические свойства сталей, применяемых в краностроении(НТУ "ХПИ", 2013) Беликов, С. Б.; Шевченко, В. Г.; Рягин, С. Л.Influence of a temperature and deformation speed on mechanical characteristics of 09G2S steel had been studied. It was shown that influence of the temperature and deformation speed on mechanical characteristics of specific steels can differ from classical ideas. Plastic deformation take place at low temperature as well.
