Influence of the structural state on mechanical properties of tin babbit under upsetting

Abstract: The behavior of a material in extreme regimes of operation in large constructions can be calculated with the use of modern software codes (ANSYS, DEFORM, LS-Dyna). However, they do not have a sufficient basis for the properties of metals and alloys. Therefore, it is necessary to input experimental mechanical properties of a studied material for an adequate description of a process. The present work aims to obtain the mechanical properties of babbit Sn 11 % Sb 5,5 % Cu in different structural states for a use i… Show more

“…As the material for the study, we selected the Sn11Sb5.5Cu Babbitt (11 % Sb, 5.5 % Cu, the rest is Sn) produced by conventional casting in a chill mold at different crystallization rates [20]. An increase in the crystallization rate as a result of cooling in water enabled varying the samples microstructure.…”

“…We assigned the properties of an absolutely rigid body to the punch and the die. The rod material was considered ductile, and its behavior was described by the experimental curves obtained during the upsetting of the Sn11Sb5.5Cu Babbitt samples at room temperature [20]. The contact conditions at the «rod-die» and «rod-punch» boundaries were described by Siebel's friction model [21].…”

“…В качестве материала исследования был выбран баббит Б83 (11 % Sb, 5,5 % Cu, остальное -Sn, вес.%), полученный обычным литьем в кокиль. Микроструктура баббита варьировалась скоростью охлаждения при кристаллизации [18]. Оснастка для РКУП состояла из матрицы с вертикальным и горизонтальным каналами, пересекающимися под прямым углом, и пуансона, находящегося в вертикальном канале матрицы.…”

“…Пуансону и матрице задавались свойства абсолютно жесткого тела. Материал прутка принимался пластичным, и описывался экспериментальными кривыми, полученными при сжатии образцов из баббита Б83 при комнатной температуре [18]. Контактные условия на границах «пруток -матрица» и «пруток -пуансон» описывались моделью трения по Зибелю [19].…”
