This paper aims to investigate the properties of aluminum-based composite Al2O3/SiC ceramics using new severe plastic deformation (SPD) methods and finite element method. research work also focused on accuracy simulation results in manufacturing reinforced ceramic. The latest method was developed by repetitive press-roll forming (RPRF) for processing ceramic-reinforced materials. simulations we...

Severe plastic deformation (SPD) is one of the processes used to refine the microstructure of materials. Equal Channel Angular Extrusion (ECAE) is the most common method of SPD. In this study, AL-6063grain refinement was performed using the Equal Channel Angular Extrusion method. The material was extruded up to 6 passes at a temperature of 200°C following route A. A suitable die sets equipped w...

High-purity Ni was processed by high-pressure torsion (HPT) at room temperature under an imposed pressure of 6.0 GPa and a rotation rate 1 rpm through 1/4 to 10 turns, samples were then examined using Electron Back-Scattered Diffraction (EBSD) microhardness measurements. The results show that the grain size low-angle boundaries (LAGBs) gradually decrease with growth HPT revolutions while values...

A Mg-8.2Gd-3.8Y-1.0Zn-0.4Zr (wt.%) alloy is processed by solution treatment and high pressure torsion (HPT) at room temperature to produce a nanostructured light material with hardness. The stability of this subsequently tested through isochronal annealing for 0.5 h 373 K 673 K. results reveal thermal that vastly superior conventional Mg-based alloys severe plastic deformation: the grain size r...

In this research the constrained groove pressing (CGP) process as a severe plastic deformation (SPD) method was applied on commercially pure aluminum plates. According to the principle of CGP, a material is subjected to repetitive shear deformation by utilizing asymmetrically grooved dies and flat dies which are constrained by a channel. Each complete groove pressing pass consists of four press...

• The metal dusting corrosion resistance of Fe-based alloy is significantly improved. Development at each step explained by SEM, Raman and FIB/TEM/EDS/EELS. NS-SPD yields high density defects in the deformation zone near surface. Thermochemical treatment promotes formation a protective Cr-rich oxide scale. Combined thermochemical has been used to improve Incoloy 800. After testing under infinit...

Magnesium and its alloys are the most investigated materials for solid-state hydrogen storage in form of metal hydrides, but there still unresolved problems with kinetics thermodynamics hydrogenation dehydrogenation this group materials. Severe plastic deformation (SPD) methods, such as equal-channel angular pressing (ECAP), high-pressure torsion (HPT), intensive rolling, fast forging, have bee...

For this paper, studies of the microstructure as well mechanical and biological properties bioinert titanium, zirconium, niobium alloys in their nanostructured (NS) ultrafine-grained (UFG) states have been completed. The NS UFG were formed by a combined two-step method severe plastic deformation (SPD), first with multidirectional forging (MDF) or pressing into symmetrical channel (PSC) at given...
