Here, we report the fabrication of nanocrystalline (NC) Al0.1CoCrFeNi high entropy alloy and subsequent small-scale plastic deformation behavior via nano-pillar compression tests. Exceptional strength was realized for the NC HEA compared to pure Ni of similar grain sizes. Grain boundary mediated deformation mechanisms led to high strain rate sensitivity of flow stress in the nanocrystalline HEA.<\/jats:p>","DOI":"10.3390\/e20110889","type":"journal-article","created":{"date-parts":[[2018,11,21]],"date-time":"2018-11-21T11:23:27Z","timestamp":1542799407000},"page":"889","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":11,"title":["Small-Scale Plastic Deformation of Nanocrystalline High Entropy Alloy"],"prefix":"10.3390","volume":"20","author":[{"given":"Sanghita","family":"Mridha","sequence":"first","affiliation":[{"name":"Department of Materials Science and Engineering, University of North Texas, Denton, TX 76203, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mageshwari","family":"Komarasamy","sequence":"additional","affiliation":[{"name":"Department of Materials Science and Engineering, University of North Texas, Denton, TX 76203, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Sanjit","family":"Bhowmick","sequence":"additional","affiliation":[{"name":"Bruker Nano Surfaces, Minneapolis, MN 55344, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Rajiv S.","family":"Mishra","sequence":"additional","affiliation":[{"name":"Department of Materials Science and Engineering, University of North Texas, Denton, TX 76203, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1954-0045","authenticated-orcid":false,"given":"Sundeep","family":"Mukherjee","sequence":"additional","affiliation":[{"name":"Department of Materials Science and Engineering, University of North Texas, Denton, TX 76203, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2018,11,20]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"299","DOI":"10.1002\/adem.200300567","article-title":"Nanostructured high-entropy alloys with multiple principal elements: Novel alloy design concepts and outcomes","volume":"6","author":"Yeh","year":"2004","journal-title":"Adv.
