Аннотация: A study was made for the modes of production technology of wire from the Pd-5Ni alloy with a diameter of 0.075 mm for catchment gauzes and the influence of pressure treatment parameters on the structure and properties of the obtained deformed semi-finished products was investigated. Computer models of cold sectional rolling of workПоказать полностьюpieces and subsequent drawing of Pd-5Ni alloy wire from them have been developed. The models made it possible to evaluate the stress–strain state of the metal during its processing, to determine the force conditions of rolling and drawing, and also to predict the destruction of workpieces using the Cockcroft-Latham criterion. Testing of the simulation results was carried out on industrial equipment, consisting of a pneumatic hammer to obtain a workpiece of a square section of 30 × 30 mm, three sectional rolling mills with a rhombus-square system to obtain a workpiece of a square section of 3.45 × 3.45 mm and three drawing mills. On the first two rolling mills, the workpiece was rolled by sequential movement along the calibers, and on the third mill, rolling was carried out in a continuous mode. To obtain a wire with a diameter of 0.075 mm from rolled wire obtained by rolling at the third mill, the technological modes of drawing were studied. On the first mill, wire drawing was carried out from a diameter of 3.50 mm to a diameter of 1.45 mm. Then, after annealing on the second mill, drawing was carried out from a diameter of 1.45 mm to a diameter of 0.175 mm. Next, the wire was subjected to copper plating, and at the third stage, a wire of a given diameter was obtained according to the modes obtained by computer simulation. During drawing, wire breaks were not observed, and its properties met the requirements of regulatory documents for wire from palladium alloys intended for the manufacture of catchment gauzes.
