Cold drawing schedules for RSt 34-2 (1.0034) steel wire for correction of overheating defects and breakless ensuring

“…The analysis of wire drawing current state and prospects shows [1] that in the world there is a tendency to expand the range of materials by chemical composition, initial state, finishing mechanical properties and the attendant decrease in production. Development of drawing in small batches complex technologies, which also include improvement of operations previous and subsequent to drawing by using thermomechanical, pulse, electroerosion processing [2][3][4][5][6], determining optimal metal processing power schedules [7][8][9][10], allows to make wire and deformed semi-finished products from operational properties and schedules [11][12][13][14][15], which are inaccessible to the multihole drawing machine. Achieving these goals is facilitated by the increasing use of mathematical modeling to assess the stress-strain and thermal state of materials, taking into account their plastic and thermophysical properties, accumulated damage and cracks, followed by assessment of their healing properties [16][17][18][19][20].…”

Nickel-Based Slag-Remelted Superalloy for Ti-Alloys Isothermal Forging Die-Tool

“…In this regard, choosing die material for such conditions should be based on the improvement of both the forgings die forging, as well as die materials manufacturing. In the first case, the research purpose should be to reduce tool wear, electricity consumption, materials plastic properties control and forming power modes [17][18][19][20][21][22]. It is necessary to take into account the low technological performance of die materials, which is manifested in the fact that severe plastic deformation with high reduction leads to their fracture due to significant stresses arising in metals [23][24][25][26][27].…”
