After DryLP treatment of the laser-welded 2024 aluminum alloy, the softened weld metal recovered to the original hardness of base metal, while residual tensile stress in the weld metal and heat-affected zone changed to compressive stresses. As a result, DryLP treatment improved the fatigue performances of welded specimens with and without the weld reinforcement almost equally. The fatigue life almost doubled at a stress amplitude of 180 MPa and increased by a factor of more than 50 at 120 MPa. DryLP was found to be more effective for improving the fatigue performance of laser-welded aluminum specimens with welding defects at lower stress amplitudes, as stress concentration at the defects did not significantly influence the fatigue performance.","subitem_description_type":"Abstract"}]},"item_8_publisher_8":{"attribute_name":"出版者","attribute_value_mlt":[{"subitem_publisher":"MDPI "}]},"item_8_relation_14":{"attribute_name":"DOI","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"10.3390/met9111192","subitem_relation_type_select":"DOI"}}]},"item_8_relation_17":{"attribute_name":"関連サイト","attribute_value_mlt":[{"subitem_relation_type_id":{"subitem_relation_type_id_text":"https://doi.org/10.3390/met9111192","subitem_relation_type_select":"DOI"}}]},"item_8_source_id_9":{"attribute_name":"ISSN","attribute_value_mlt":[{"subitem_source_identifier":"2075-4701","subitem_source_identifier_type":"ISSN"}]},"item_access_right":{"attribute_name":"アクセス権","attribute_value_mlt":[{"subitem_access_right":"metadata only access","subitem_access_right_uri":"http://purl.org/coar/access_right/c_14cb"}]},"item_creator":{"attribute_name":"著者","attribute_type":"creator","attribute_value_mlt":[{"creatorNames":[{"creatorName":"Sano, Tomokazu"}],"nameIdentifiers":[{"nameIdentifier":"999861","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Eimura, Takayuki"}],"nameIdentifiers":[{"nameIdentifier":"999862","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Hirose, Akio"}],"nameIdentifiers":[{"nameIdentifier":"999863","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Kawahito, Yosuke"}],"nameIdentifiers":[{"nameIdentifier":"999864","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Katayama , Seiji"}],"nameIdentifiers":[{"nameIdentifier":"999865","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Arakawa, Kazuto"}],"nameIdentifiers":[{"nameIdentifier":"999866","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Masaki, Kiyotaka"}],"nameIdentifiers":[{"nameIdentifier":"999867","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Shiro, Ayumi"}],"nameIdentifiers":[{"nameIdentifier":"999868","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Shobu , Takahisa"}],"nameIdentifiers":[{"nameIdentifier":"999869","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Sano, Yuji"}],"nameIdentifiers":[{"nameIdentifier":"999870","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Ayumi, Shiro","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"999871","nameIdentifierScheme":"WEKO"}]},{"creatorNames":[{"creatorName":"Takahisa, Shobu","creatorNameLang":"en"}],"nameIdentifiers":[{"nameIdentifier":"999872","nameIdentifierScheme":"WEKO"}]}]},"item_language":{"attribute_name":"言語","attribute_value_mlt":[{"subitem_language":"eng"}]},"item_resource_type":{"attribute_name":"資源タイプ","attribute_value_mlt":[{"resourcetype":"journal article","resourceuri":"http://purl.org/coar/resource_type/c_6501"}]},"item_title":"Improving Fatigue Performance of Laser-Welded 2024-T3 Aluminum Alloy Using Dry Laser Peening","item_titles":{"attribute_name":"タイトル","attribute_value_mlt":[{"subitem_title":"Improving Fatigue Performance of Laser-Welded 2024-T3 Aluminum Alloy Using Dry Laser Peening"}]},"item_type_id":"8","owner":"1","path":["1"],"pubdate":{"attribute_name":"公開日","attribute_value":"2020-03-23"},"publish_date":"2020-03-23","publish_status":"0","recid":"79622","relation_version_is_last":true,"title":["Improving Fatigue Performance of Laser-Welded 2024-T3 Aluminum Alloy Using Dry Laser Peening"],"weko_creator_id":"1","weko_shared_id":-1},"updated":"2023-05-15T19:43:30.081065+00:00"}
