20.500.12556/RUL-140842 Effect of dual-stage ageing and RRA treatment on the three-body abrasive wear of the AW7075 alloy Vpliv dvostopenjskega staranja in obdelave RRA na abrazivno obrabo med tremi telesi pri zlitini AW7075 The paper presents an analysis of the influence of the heat treatment state on the abrasive wear of the AW7075 aluminium alloy. To determine the hardening state, the material hardness was measured. It was found that hardness is not the only factor that influences this type of wear. For this reason, the influence of the emerging microstructure is also analysed in the considerations. After tribological tests, microscopic observations of surface features were carried out to determine the dominant mechanisms of surface damage. The results were extended by the hardness distribution carried out on the cross-section. There were no changes in hardness that could be related to either strain hardening or structural changes caused by friction. aluminum alloys AW7075 abrasive wear heat treatment hardness microstructure aluminijeve zlitine abrazivna obraba trdota mikrostrukture true false true Angleški jezik Slovenski jezik Članek v reviji 2022-09-20 08:04:15 2022-09-20 08:04:21 2022-09-21 03:43:51 0000-00-00 00:00:00 2022 0 0 Str. 493-505 no. 7/8 Vol. 68 Jul./Aug. 2022 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 2022-07-01 669 0039-2480 10.5545/sv-jme.2022.142 122006787 Lachowicz,_Leśniewski,_Lachowicz-Effect_of_dual-stage_ageing_and_RRA_treatment_on_the_three-body_abrasive_wear_of_the_AW7075_alloy.pdf Lachowicz,_Leśniewski,_Lachowicz-Effect_of_dual-stage_ageing_and_RRA_treatment_on_the_three-body_abrasive_wear_of_the_AW7075_alloy.pdf 1 1748BF46CFC2D0337292129B53F562C6 02cd0a742071bfaaa19c0d06ce0095bc45d566a9bc7639fb7434a316fe781071 4a92dd25-38aa-11ed-92af-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=161656 https://www.sv-jme.eu/sl/article/effect-of-dual-stage-aging-and-rra-treatment-on-the-three-body-abrasive-wear-of-the-aw7075-alloy/ 1 ffada7d5-38a9-11ed-92af-00155dcfd717 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=161655 Fakulteta za strojništvo Strojniški vestnik 0 0 0
