Autor: Przemysław Snopiński, Michal Kotoul, Jindřich Petruška, Stanislav Rusz, Krzysztof Żaba, Ondřej Hilšer

Publikováno v: Scientific Reports, Vol 13, Iss 1, Pp 1-16 (2023)

Abstract In this study, microstructural features direct metal laser melted (DMLM) aluminium–silicon-magnesium (AlSi10Mg) are investigated using advanced transmission electron microscopy (TEM) and high-resolution TEM (HRTEM). The focus is on post-pr

Evolution of Microstructure, Texture and Corrosion Properties of Additively Manufactured AlSi10Mg Alloy Subjected to Equal Channel Angular Pressing (ECAP)

Autor: Przemysław Snopiński, Anna Woźniak, Dariusz Łukowiec, Krzysztof Matus, Tomasz Tański, Stanislav Rusz, Ondřej Hilšer

Publikováno v: Symmetry, Vol 14, Iss 4, p 674 (2022)

In the selective laser melting process (SLM), the region irradiated by the laser beam is melted and quickly solidified, forming solidification lines (laser scan tracks) with symmetrical shapes. Because of the unique (rapid) crystallization conditions

Influence of Severe Plastic Deformation on Mechanical Properties and Structure of Aluminium Alloys

Autor: Ondřej Hilšer, Stanislav Rusz, Radek čada, Michal Salajka, Jan Dutkiewicz

Publikováno v: Transactions of the VŠB-Technical University of Ostrava, Mechanical Series, Vol 62, Iss 1, Pp 26-37 (2016)

Article is devoted to analysis of ECAP (Equal Channel Angular Pressing) method, which uses a high degree of deformation to achieve a very fine-grained structure of formed material. Utilization of The ECAP technology enables attainment of required pro

STRUCTURE AND PROPERTIES OF AZ31 MAGNESIUM ALLOY AFTER COMBINATION OF HOT EXTRUSION AND ECAP

Autor: Ondřej Hilšer, Stanislav Rusz, Wojciech Maziarz, Jan Dutkiewicz, Tomasz Tański, Przemysław Snopiński, Jan Džugan

Publikováno v: Acta Metallurgica Slovaca, Vol 23, Iss 3 (2017)

Equal channel angular pressing (ECAP) method was used for achieving very fine-grained structure and increased mechanical properties of AZ31 magnesium alloy. The experiments were focused on the, in the initial state, hot extruded alloy. ECAP process w

Study of the Microstructure, Tensile Properties and Hardness of AZ61 Magnesium Alloy Subjected to Severe Plastic Deformation

Autor: Ondřej Hilšer, Stanislav Rusz, Pavel Szkandera, Lubomír Čížek, Martin Kraus, Jan Džugan, Wojciech Maziarz

Publikováno v: Metals, Vol 8, Iss 10, p 776 (2018)

Hot extruded (EX) AZ61 magnesium alloy was processed by the twist channel angular pressing (TCAP) method, which combines equal channel angular pressing (ECAP) and twist extrusion (TE) processes and significantly improves the efficiency of the grain r
