The effects on the deposition surface oxidation, geometry, burn out rate of Mg, pores, microstructure, mechanical properties and fracture mechanisms were investigated. The results show that, when the Mg content increased, the surface oxidation degree increased; a \u201cwave\u201d-shaped deposition layer occurred when the Mg content reached 8%. When the Mg content was more than 6%, the burning loss rate of the Mg element increased significantly. With the increase of Mg content, the number of pores first decreased and then increased, and the size first decreased and then increased. When the Mg content reached 7% or above, obvious crystallization hot cracks appeared in the deposit bodies. When the Mg content increased, the precipitated phase (FeMn)Al6 and \u03b2(Mg2Al3) increased, and the grain size increased. When the Mg content was 6%, the comprehensive mechanical properties were best. The horizontal tensile strength, yield strength and elongation were 310 MPa, 225 MPa and 17%, respectively. The vertical tensile strength, yield strength and elongation were 300 MPa, 215 MPa and 15%, respectively. The fracture morphology was a ductile fracture.<\/jats:p>","DOI":"10.3390\/ma12244160","type":"journal-article","created":{"date-parts":[[2019,12,12]],"date-time":"2019-12-12T03:20:16Z","timestamp":1576120816000},"page":"4160","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":33,"title":["Effect of Mg Content on Microstructure and Properties of Al\u2013Mg Alloy Produced by the Wire Arc Additive Manufacturing Method"],"prefix":"10.3390","volume":"12","author":[{"given":"Lingling","family":"Ren","sequence":"first","affiliation":[{"name":"College of Metallurgy, Northeastern University, Shenyang 110000, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Huimin","family":"Gu","sequence":"additional","affiliation":[{"name":"College of Metallurgy, Northeastern University, Shenyang 110000, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Wei","family":"Wang","sequence":"additional","affiliation":[{"name":"Inner Mongolia Metal Research Institute, Baotou 014000, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Shuai","family":"Wang","sequence":"additional","affiliation":[{"name":"College of Metallurgy, Northeastern University, Shenyang 110000, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Chengde","family":"Li","sequence":"additional","affiliation":[{"name":"College of Metallurgy, Northeastern University, Shenyang 110000, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Zhenbiao","family":"Wang","sequence":"additional","affiliation":[{"name":"North East Industrial Materials &amp; Metallurgy Co., Ltd, Fushun 113000, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yuchun","family":"Zhai","sequence":"additional","affiliation":[{"name":"College of Metallurgy, Northeastern University, Shenyang 110000, China"},{"name":"North East Industrial Materials &amp; Metallurgy Co., Ltd, Fushun 113000, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Peihua","family":"Ma","sequence":"additional","affiliation":[{"name":"College of Metallurgy, Northeastern University, Shenyang 110000, China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2019,12,11]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"859","DOI":"10.1080\/02670836.2018.1455012","article-title":"A review of wire arc additive manufacturing an advances in wire arc additive manufacturing of aluminium","volume":"34","author":"Derekar","year":"2018","journal-title":"Mater.
