“…Firstly, the PTCAP process produced a UFG thick-walled tube, and then the TBE process reduced its thickness [21]. Eftekhari et al researched the hot deformation behavior of AZ31 Mn alloy, thin walls under the combined process of PTCAP and TBE [22]. The bulge test was utilized to assess the bursting pressure of tubes post-PTCAP process.…”

The Parallel Tubular Channel Angular Pressing Process (PTCAP) has emerged as a promising method for refining the grain structure and enhancing the mechanical properties of metallic mate-rials through severe plastic deformation. This study focuses on a comprehensive investigation of the PTCAP process, combining experimental and numerical analysis to gain insights into its underlying mechanisms. Experimental investigations involve processing a commercially pure copper tube using PTCAP under controlled conditions. In parallel, an explicit numerical analysis is developed using ABAQUS software to simulate the deformation behavior during PTCAP. The model incorporates material constitutive equations and accounts to describe the material response under high strain rates and large deformations. The research aims to investigate how multi-pass PTCAP affects hardness, strain homogeneity, and stress distribution. A comparison between the load punch from the experimental and FEM is conducted to validate the FEM results, and there is a good correlation between both. Hardness measurements are conducted at various stages to quantify the changes in material hardness resulting from the successive PTCAP passes. The hardness of the Cu tube increased by 63.45, 94.51, 103.98, and 105.64 % after 1 to 4 passes, respectively.

“…Some basic works on principles and methods of SPD can be found in the literature such as works of Valiev et al [5,6]. Equal channel angular pressing (ECAP) [7,8], high-pressure torsion cyclic closed-die forging [9] and parallel tubular channel angular pressing (PTCAP) [10,11] are the main methods which have been used for modification and enhancing properties of the as-cast AZ31.…”

A novel one-pass integrated severe plastic deformation method, entitled extrusion compression angular pressing forward extrusion (ECAP-FE), was designed and used for fabricating a fine-grained as-cast AZ31 Mg alloy. Subsequently, mechanical (room temperature compression, tensile and microhardness) and microstructural properties of the processed sample were investigated in detail. In addition, a finite element simulation of the proposed method was carried out for evaluating the equivalent plastic strain and strain rate distribution. The results showed that the ECAP-FE method is a powerful method for processing the ultrafine-grained as-cast AZ31 Mg alloy in a single pass to achieve a uniform and fine microstructure with enhanced mechanical properties. Therefore, it appears that the proposed method has a great potential to a wide range of industrial applications.
