When the porous branches were compressed along its building direction, the tree column structures-type AlSi10Mg alloy branches collapsed twice, which had typical elastic, shear, collapse, and densification stages. The compressive stress concentration at the interface between the support and the porous body caused the fracture of the tree column structures-type AlSi10Mg alloy branches. The fracture surface indicated that the prepared tree-type branches were distributed with different shapes of dimples, and the Si content inside the dimples was higher than that of the edge. The morphology of the Al-Si eutectic structure formed by SLM and the stress concentration at the Al\/Al-Si-eutectic interface affected the fracture morphology and Si content distribution.<\/jats:p>","DOI":"10.3390\/ma13183969","type":"journal-article","created":{"date-parts":[[2020,9,8]],"date-time":"2020-09-08T09:03:48Z","timestamp":1599555828000},"page":"3969","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":7,"title":["Failure Analysis of the Tree Column Structures Type AlSi10Mg Alloy Branches Manufactured by Selective Laser Melting"],"prefix":"10.3390","volume":"13","author":[{"given":"Peikang","family":"Bai","sequence":"first","affiliation":[{"name":"School of Materials Science and Engineering, North University of China, Taiyuan 030051, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5372-1424","authenticated-orcid":false,"given":"Pengcheng","family":"Huo","sequence":"additional","affiliation":[{"name":"School of Materials Science and Engineering, North University of China, Taiyuan 030051, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Taotao","family":"Kang","sequence":"additional","affiliation":[{"name":"Capital Aerospace Machinery Corporation Limited, Beijing 100072, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Zhanyong","family":"Zhao","sequence":"additional","affiliation":[{"name":"School of Materials Science and Engineering, North University of China, Taiyuan 030051, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Wenbo","family":"Du","sequence":"additional","affiliation":[{"name":"National Key Laboratory for Remanufacturing, Army Academy of Armored Forces, Beijing 100072, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Minjie","family":"Liang","sequence":"additional","affiliation":[{"name":"School of Materials Science and Engineering, North University of China, Taiyuan 030051, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yuxin","family":"Li","sequence":"additional","affiliation":[{"name":"School of Materials Science and Engineering, North University of China, Taiyuan 030051, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Haihong","family":"Liao","sequence":"additional","affiliation":[{"name":"School of Materials Science and Engineering, North University of China, Taiyuan 030051, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yun","family":"Liu","sequence":"additional","affiliation":[{"name":"School of Materials Science and Engineering, North University of China, Taiyuan 030051, China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2020,9,8]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"1414","DOI":"10.1016\/j.jallcom.2017.11.020","article-title":"Gradient in microstructure and mechanical property of selective laser melted AlSi10Mg","volume":"735","author":"Liu","year":"2018","journal-title":"J.
