Tensile Fracture Behavior of Progressively-Drawn Pearlitic Steels

open access: yesMetals, 2016
In this paper a study is presented of the tensile fracture behavior of progressively-drawn pearlitic steels obtained from five different cold-drawing chains, including each drawing step from the initial hot-rolled bar (not cold-drawn at all) to the final

On the Mechanism of Cold-Drawing

open access: yesjournal of the Japan Society for Testing Materials, 1959
As the simplest and common model accounting for the mechanism of the cold-drawing of crystalline high polymeric substances, the usual theory for the rubber elasticity of vulcanized rubber was applied. The theoretical relationships between tensile strength or elongation at break and drawing ratio of drawn fibers were introduced.

The Role of Overloading on the Reduction of Residual Stress by Cyclic Loading in Cold-Drawn Prestressing Steel Wires

open access: yesApplied Sciences, 2017
Prestressing steel wires are commonly used as reinforcement elements in structures bearing fatigue loads. These wires are obtained by a conforming process called cold drawing, where a progressive reduction of the wire diameter is produced, causing ...

Process Parameter Optimization for Minimizing Springback in Cold Drawing Process of Seamless Tubes Using Advanced Optimization Algorithms [PDF]

open access: yesJournal of Soft Computing in Civil Engineering, 2018
In tube drawing process, a tube is pulled out through a die and a plug to reduce its diameter and thickness as per the requirement. Dimensional accuracy of cold drawn tubes plays a vital role in the further quality of end products and controlling ...

Synchrotron strain scanning for residual stress measurement in cold-drawn steel rods

open access: yes, 2011
Cold-drawn steel rods and wires retain significant residual stresses as a consequence of the manufacturing process. These residual stresses are known to be detrimental for the mechanical properties of the wires and their durability in aggressive ...

Chemical preparation of tubes before cold drawing

open access: yes, 2021
Prior to the technological process of cold drawing of tubes through dies, a very important part is preparation for drawing and pre-treatment of tubes. In the production of cold drawn tubes, pre-treatment involves the chemical removing of impurities and ...
