Analysis of Causes of Defects Appearance in Wire Drawing
Original language description
In the manufacture of wires designed for the welding of low-alloy fine-grain steels, multiple internal discontinuities appear during some periods that are the cause of major failures (cracking) of the wires. To establish the causes of this phenomenon, a complex analysis was performed making use of light and electron microscopy, metallography, microfractography, computerized tomography and hardness measurement. The analysis revealed that wire cracking in course of wire drawing was due to the superposition of the effects of an inappropriate structure of the initial intermediate product (the presence of polyhedral grains of hard bainitic phase) and unsuitable conditions of the forming process.
