For this purpose, S170 steel particles with a diameter of 0.5 mm and a hardness of 56 HRC were used with different air pressures and mass flows, providing Almen intensity levels between 10A and 28A. The treated surfaces were studied in terms of surface integrity at macro- and microscopic levels, and the surface roughness, microhardness profiles, and residual stresses of each treated surface layer were recorded. Research results reveal significant differences between the properties recorded in the surface integrity examination, which are based on the selected shot peening parameters. This means that these parameters substantially impact the surface conditions and the surface layer. The microscopic analysis confirmed that the sharpest treatment conditions result in surface deformations which may cause cracks and subsequently lead to the mechanical part's collapse"},{"@xml:lang":"sl","#text":"Namen prispevka je predstaviti dve vrsti aluminijevih zlitin AlCu4PbMgMn (2007-T351) in AlSi1MgMn (6082-T651), ki sta bili mikro površinsko utrjeni z različnimi pogoji udarnega utrjevanja s kinetično energijo kroglic.

Cilj raziskave je, da z eksperimentalnimi metodami raziščemo zvezo med pogoji udarnega utrjevanja aluminijevih zlitin ter hrapavostjo in topografijo površine z mikroskopskimi preiskavami poškodb na površini, podprto z analizo mikrostrukture, trdote in zaostalih napetosti"}],"edm:type":"TEXT","dc:type":[{"@xml:lang":"sl","#text":"znanstveno časopisje"},{"@xml:lang":"en","#text":"journals"},{"@rdf:resource":"http://www.wikidata.org/entity/Q361785"}]},"ore:Aggregation":{"@rdf:about":"http://www.dlib.si/?URN=URN:NBN:SI:doc-O25DY8VD","edm:aggregatedCHO":{"@rdf:resource":"URN:NBN:SI:doc-O25DY8VD"},"edm:isShownBy":{"@rdf:resource":"http://www.dlib.si/stream/URN:NBN:SI:doc-O25DY8VD/281c38d7-f9a0-4455-aeb1-b31e7d3c7bc5/PDF"},"edm:rights":{"@rdf:resource":"http://rightsstatements.org/vocab/InC/1.0/"},"edm:provider":"Slovenian National E-content Aggregator","edm:intermediateProvider":{"@xml:lang":"en","#text":"National and University Library of Slovenia"},"edm:dataProvider":{"@xml:lang":"sl","#text":"Univerza v Ljubljani, Fakulteta za strojništvo"},"edm:object":{"@rdf:resource":"http://www.dlib.si/streamdb/URN:NBN:SI:doc-O25DY8VD/maxi/edm"},"edm:isShownAt":{"@rdf:resource":"http://www.dlib.si/details/URN:NBN:SI:doc-O25DY8VD"}}}}
