In the present work an attempt has been made to join these materials via the friction welding method, i.e. one of the solid phase joining processes. In particular, the present paper describes the optimisation of friction welding parameters so that the intermetallic layer is narrow and joints of acceptable quality can be produced for a dissimilar joint between Al-Mg-Si alloy (AA6061) and Ni-Cr-Mo low alloy steel, using a design of experiment method. The effect of post-weld heat treatment on the tensile strength of the joints was then clarified. It was concluded that the friction time strongly affected the joint tensile strength, the latter decreasing rapidly with increasing friction time. The highest strength was achieved using the shortest friction time. The highest joint strength was greater than that of the AA6061 substrate in the as welded condition. This is due to the narrow width of the brittle intermetallic layer generated, which progressed from the peripheral (outer surface) region to the centreline region of the joint with increasing friction time. The joints in the as welded condition could be bent without cracking in a bend test. The joint tensile strength in the as welded condition was increased by heat treatment at 423 K (150\u00b0 C), and then it decreased when the heat treatment temperature exceeded 423 K. All joints fractured in the AA6061 substrate adjacent to the interface except for the joints heated at 773 K (500\u00b0 C). The joints fractured at the interface because of the occurrence of a brittle intermetallic compound phase.", "subitem_description_type": "Abstract"}]}, "item_3_full_name_183": {"attribute_name": "\u8457\u8005\u5225\u540d", "attribute_value_mlt": [{"nameIdentifiers": [{"nameIdentifier": "41147", "nameIdentifierScheme": "WEKO"}], "names": [{"name": "\u51a8\u58eb, \u660e\u826f"}]}]}, "item_3_publisher_212": {"attribute_name": "\u51fa\u7248\u8005", "attribute_value_mlt": [{"subitem_publisher": "Maney Publishing"}]}, "item_3_relation_191": {"attribute_name": "DOI", "attribute_value_mlt": [{"subitem_relation_type_id": {"subitem_relation_type_id_text": "http://dx.doi.org/10.1179/136217104225017166", "subitem_relation_type_select": "DOI"}}]}, "item_3_select_195": {"attribute_name": "\u8457\u8005\u7248\u30d5\u30e9\u30b0", "attribute_value_mlt": [{"subitem_select_item": "author"}]}, "item_3_subject_196": {"attribute_name": "\u65e5\u672c\u5341\u9032\u5206\u985e\u6cd5", "attribute_value_mlt": [{"subitem_subject": "566", "subitem_subject_scheme": "NDC"}]}, "item_creator": {"attribute_name": "\u8457\u8005", "attribute_type": "creator", "attribute_value_mlt": [{"creatorNames": [{"creatorName": "Fuji, A"}], "nameIdentifiers": [{"nameIdentifier": "41146", "nameIdentifierScheme": "WEKO"}]}]}, "item_files": {"attribute_name": "\u30d5\u30a1\u30a4\u30eb\u60c5\u5831", "attribute_type": "file", "attribute_value_mlt": [{"accessrole": "open_date", "date": [{"dateType": "Available", "dateValue": "2016-11-22"}], "displaytype": "detail", "download_preview_message": "", "file_order": 0, "filename": "No.15-NiCrMo.pdf", "filesize": [{"value": "1.0 MB"}], "format": "application/pdf", "future_date_message": "", "is_thumbnail": false, "licensetype": "license_free", "mimetype": "application/pdf", "size": 1000000.0, "url": {"label": "No.15-NiCrMo.pdf", "url": "https://kitami-it.repo.nii.ac.jp/record/7949/files/No.15-NiCrMo.pdf"}, "version_id": "657d674e-b02c-4875-a070-f72775763986"}]}, "item_keyword": {"attribute_name": "\u30ad\u30fc\u30ef\u30fc\u30c9", "attribute_value_mlt": [{"subitem_subject": "DISSIMILAR MATERIAL JOINING", "subitem_subject_scheme": "Other"}, {"subitem_subject": "ALUMINIUM ALLOYS", "subitem_subject_scheme": "Other"}, {"subitem_subject": "LOW ALLOY STEELS", "subitem_subject_scheme": "Other"}, {"subitem_subject": "BRITTLE INTERMETALLIC COMPOUND INTERLAYER", "subitem_subject_scheme": "Other"}, {"subitem_subject": "FRICTION WELDING", "subitem_subject_scheme": "Other"}]}, "item_language": {"attribute_name": "\u8a00\u8a9e", "attribute_value_mlt": [{"subitem_language": "eng"}]}, "item_resource_type": {"attribute_name": "\u8cc7\u6e90\u30bf\u30a4\u30d7", "attribute_value_mlt": [{"resourcetype": "journal article", "resourceuri": "http://purl.org/coar/resource_type/c_6501"}]}, "item_title": "Friction welding of Al\u2013Mg\u2013Si alloy to Ni\u2013Cr\u2013Mo low alloy steel", "item_titles": {"attribute_name": "\u30bf\u30a4\u30c8\u30eb", "attribute_value_mlt": [{"subitem_title": "Friction welding of Al\u2013Mg\u2013Si alloy to Ni\u2013Cr\u2013Mo low alloy steel"}]}, "item_type_id": "3", "owner": "1", "path": ["1"], "permalink_uri": "https://kitami-it.repo.nii.ac.jp/records/7949", "pubdate": {"attribute_name": "\u516c\u958b\u65e5", "attribute_value": "2015-09-02"}, "publish_date": "2015-09-02", "publish_status": "0", "recid": "7949", "relation": {}, "relation_version_is_last": true, "title": ["Friction welding of Al\u2013Mg\u2013Si alloy to Ni\u2013Cr\u2013Mo low alloy steel"], "weko_shared_id": 3}
