Abstract

A novel severe plastic deformation (SPD) process for manufacturing high strength multilayer tubes titled accumulative tube-bonding (ATB) is proposed in this article. By conducting numerous runs of the ATB process, grain refinement as well as mechanical characteristics were investigated experimentally and numerically. The original tube size sample had a 200 mm length, 25 mm diameter and a thickness of 3-mm. ATB procedure involved three passes of the tube through the die. After the third pass, the strength gradually increased significantly. The grain size of copper tube sample was reduced to 133 nm after three passes of ATB, which was confirmed by electron beam electron backscatter diffraction. Mechanical properties such as ductility, ultimate tensile strength, and hardness were also studied. The microhardness value of the tube increased after the third pass of the SPD process. The enormous increase in strength is due to a slight reduction in ductility. The tube demonstrated exceptional hardness by growing its microhardness from 60 Vickers hardness number to 135 Vickers hardness number by ATB process. Samples for scanning electron microscope (SEM) were polished using a polishing machine.
