In the selective laser melting process (SLM), region irradiated by beam is melted and quickly solidified, forming solidification lines (laser scan tracks) with symmetrical shapes. Because of unique (rapid) crystallization conditions, subgrain structures, typically observed inside these lines, could also have variable geometric patterns, e.g., cellular, pentagonal, or hexagonal cellular. The exi...

AA6060 aluminum alloy was subjected to severe plastic deformation through equal-channel angular pressing (ECAP) up 8 passes via route BC. ECAPed samples isochronally annealed for 1 hour at a temperature range of 150-450 °C. The microstructure and texture the studied material were evaluated by electron backscatter diffraction, microhardness characterized Vickers testing. It found that shearing i...

This study focused on electron microscopy studies of microstructural defects formed in an additively manufactured (AM) AlSi10Mg alloy as a result post-deformation by equal channel angular pressing (ECAP), with the aim elucidating fundamental deformation mechanisms that govern plasticity both aluminium matrix and silicon phase. article process grain refinement, metastable phase transformations, ...

Ultra-fine grained and even nanostructured magnesium alloys obtained by processing with methods of severe plastic deformation (SPD) are promising biomaterials for absorbable orthopaedic implants due to their enhanced mechanical properties, adequate corrosion resistance biocompatibility. This paper presents an overview the impact most important SPD – equal-channel angular pressing (ECAP) high-pr...

Mg–2Y–0.6Nd–0.6Zr alloy was first deformed by equal channel angular pressing (ECAP), then rolled and under ultralow temperature conditions (liquid nitrogen immersion), finally annealed. Optical microscopy (OM), electron backscatter diffraction technology (EBSD), transmission (TEM) were used to analyze the evolution of multiscale microstructure changes in mechanical properties temperatures vario...

Nanostructured (NS) and ultrafine-grained (UFG) materials have high strength and relatively low ductility. Their toughness has not been comprehensively investigated. Here we report the Charpy impact behavior and the corresponding microstructural evolutions in UFG Cu with equi-axed and elongated grains which were prepared by equal channel angular pressing (ECAP) for 2 and 16 passes at room tempe...

Several physics-based models have been utilized in material design for the simulation and prediction of properties. In this study, several machine-learning (ML) approaches were used to construct a model analyze influence equal-channel angular pressing (ECAP) parameters on microstructural, corrosion mechanical behavior biodegradable magnesium alloy ZK30. The ML employed linear regression, Gaussi...

The temperature effects on the microstructural evolution of a coarse-grained Al5083 alloy during equal channel angular pressing (ECAP), were studied at ambient and high temperatures. evaluation was done using an EBSD (electron backscattering diffraction) process. grain refinement occurred as number passes increased, which had positive effect its strength. Additionally, increasing leads to decre...
