Niobium-Titanium Superconducting Wires: Nanostructures by Extrusion and Wire Drawing
Nano-fabrication is not new to the manufacturers of superconducting wires, in fact the dominant commercial superconductor, Nb-Ti, relies on a mechanically induced nano-structure for its remarkable properties. In this paper we show how these wires are manufactured so that their microstructure achieves the same scale as the superconducting vortex spacing. Recent attention on superconductors has e...
متن کاملInfluence of an Inclusion on Multi-Pass Copper Shaped-Wire Drawing by 2D Finite Element Analysis
The size and length effects of an inclusion on multi-pass copper shaped-wire drawing were investigated. For this purpose, an experimental investigation on optimal die half-angle was conducted. Based on experimental data of optimal die half-angle, wire and inclusion deformations, drawing and hydrostatic stress of copper shaped-wires that contain an inclusion were calculated by two-dimensional fi...

A Comparative Study Between Analytical, Finite Element Method and the Experimental Results in Wire Drawing of Copper
The wire drawing process is extensively used in manufacturing components such as rivet, screw, welding wire, etc. In this work, an analytical of the wire drawing process has been considered for two-stage operation. ABAQUS commercial Finite Element code has been used to obtained the drawing force. Then, The analytical and experimental results been compared. The results show a good agreement for...
متن کاملInvestigation and Simulation of Wire Non-Asymmetric Rolling Process
The non-asymmetric rolling process of copper and brass wire has been simulated with the Abaqus software. Presented finite element model in this simulation of rolling predicted output curvature and contact surface width in the non-asymmetric mode (in equality of diameter of rollers, the rotational speed of the rollers and the rollers’ surface finish). The material used in this research has strai...
