Change in Mechanical Properties During Drawing of Wire from Ni 99.6

Abstract

This paper presents the results of a study of changes in mechanical properties, namely tensile strength, yield strength and elongation when drawing a wire from NP2 nickel (Ni 99.6). The wire samples taken along the drawing route were tested for tension. Based on the test results obtained, graphs of changes in tensile strength, yield strength and elongation were plotted depending on cold work. The approximation of the graphs made it possible to obtain equations for the change in tensile strength (UTS), yield strength (0.2 US) and elongation (δ) depending on cold work (ɛ∑). The obtained dependences are recommended to be used to predict the mechanical properties of nickel wire during drawing and when developing software for designing resource-saving drawing routes.

Mathematical Modeling of Heating and Strain Aging of Steel during High-Speed Wire Drawing

“…Overall, it seems simple, but this is one of the most difficult types of metal forming. The drawing process is influenced by a large number of various factors, such as drawing speed [10], technological lubrication [11][12][13], sub-lubricating layer [14], deformation degree [15,16], drawing die [17] and drawing machine design, etc.…”
