Among different SPD techniques, Equal channel Angular Pressing has attracted the most attentions, because of applying large strain to solid bulk materials. In this research, ECAP process up to 6 passes was carried out on a pure copper and a 6012 Al-Mg-Si alloy with BC route in ECAP dies with Φ=120 and Ψ=20 and diameter of 20and 10 millimeter respectively. Moreover, X-ray diffraction (XRD) syste...

The automobile industry uses magnesium for load-bearing components due to its low density, durability, and ductility. This study investigated a nanocomposite containing Nb2O5 (3 6 wt%) nanoparticles as reinforcement with AZ31 alloy made by stir casting. A severe plastic deformation was conducted on the cast samples via equal-channel angular pressing (ECAP) after homogenization at 410 °C 24 h ag...

Equal-channel angular pressing (ECAP) was one of severe plastic deformation method in order to increase the mechanical properties solid metal without changing its dimension and adding any alloy elements. The change on ECAPed metals caused by lattice strain, so that strain investigation recommended for evaluating metals. In this study, pure titanium rod treated ECAP with Bc route two passes. Bef...

A series of tensile testing was carried out on the ultrafine grained 5083 Al alloy, which was fabricated by equal channel angular pressing (ECAP) with different ECAP strains, at low temperature superplastic (LTS) temperature of 548K. This investigation was aimed at examining the effect of the ECAP strain inducing different microstructure in the alloy on the deformation mechanisms at LTS regime....

Mechanical properties and microstructures of commercially pure titanium (CP-Ti) developed by a newly designed multi-pass equal channel angular pressing (ECAP) process and cold drawing were investigated. The ECAP apparatus was developed in order to improve the efficiency of common ECAP and the performance of finished products. A much stronger CP-Ti billet was produced by using the proposed proce...

Nowadays, equal channel angular pressing, known as the ECAP process, is one of the most popular methods for manufacturing ultra-fine grained (UFG) materials. In this paper, Ecap process has been carried out on pure copper and 6012 aluminum alloy up to six passes by route . Principal attention was paid to the influence of parameters such as diameter, material, and the height of billet on mechani...

Applications of a metallic material highly depend on its mechanical properties, which greatly the material’s grain sizes. Reducing sizes by severe plastic deformation is one efficient approaches to enhance properties material. In this paper, equal channel angular pressing (ECAP) will be reviewed illustrate effects refinement some common materials such as titanium alloys, aluminum and magnesium ...
