Tubular channel angular pressing (TCAP) is a new and novel severe plastic deformation (SPD) technique suitable for fabrication of bulk nanograined tubular materials. There are several parameters in TCAP process. The present paper investigates the effects of curvature angles, deformation ratio (= maximum radius during TCAP/ initial radius) and deformation direction on the plastic deformation beh...

In this paper the influence of different parameters on equal channel angular pressing (EADAP) of titanium alloy is investigated. In the first step the most important parameters are selected, and then a table of experiments is designed using Taguchi method. After designing the table of experiments, all of the experiments are simulated using Abacus software and the results are optimized using Tag...

Equal channel multi angular pressing (ECMAP) process is the efficient method to enhance the productivity of ultra-fine grained (UFG) materials, by increasing process continuity and as a result decreasing process required time. Comparing repetitive ECAP method, in the same period, the number of passes can be done by ECMAP. In this article, ECMAP of AL strips in two typical annealed and as receiv...

Prediction of the deformation characteristics is an important step to understand the workability of alloys during imposing large strains. In this research, severe plastic deformation of Sn-5Sb solder alloy was carried out under different t deformation conditions, including the temperature range of 298, 330, 36, 400 K and die designs. The current study applies an experimentally validated finite ...

Multilayer composites have recently attracted considerable attention due to their ability take advantage of the benefits various metallic materials simultaneously. The present study is first use parallel tubular channel angular pressing (PTCAP) as a severe plastic deformation method fabricate bimetal Al/Mg tube. This process was applied on commercially pure aluminum along with an AM60 magnesium...
