- This article introduces tube channel tensile pulling, a groundbreaking method for the severe plastic deformation (spd) procedure for tubes. By performing many runs of the Tube Channel Tensile Pulling (TCTP) process, grain refinement as well as mechanical characteristics were investigated experimentally and numerically. The original tube size sample had a 1-inch diameter and a thickness of 0.3 cm. The TCTP procedure involved four passes of the tube through the die. After the third pass, the strength gradually increased significantly. Additionally, the grain size was around 200 nm, which was confirmed by EBSD (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. Samples for Scanning Electron Microscopy (SEM) were polished using a polishing machine.
