Iron aluminides, compared to other transition metal\u2013aluminides of TM<sub>3<\/sub>-Al type, although having a higher density compared to titan-aluminides, have a lower density compared to nickel-aluminides, but also a higher ductility than both alternatives, making this material potentially effective in ballistic protection application. Density\u2013wise, this material may be a worthy alternative to armour steels, which was the aim of this study. Two materials, Fe<sub>3<\/sub>Al intermetallic compound (F3A-C) and Armox 500 armour steel were ballistically tested against tungsten-carbide (WC) armour-piercing ammunition, in accordance with STANAG 4569. After ballistic testing, microhardness and metallographic testing were performed, revealing differences in strain hardening, crack propagation mode and exit hole morphology. F3A-C ballistic resistance is similar to that of armour steel, in spite of the lower tensile and impact mechanical properties, relying on a considerably higher strain hardening rate, thermal properties and a lower density.<\/p>\n<p><a href=\"https:\/\/www.fie.undef.edu.ar\/ceptm\/wp-content\/uploads\/2024\/08\/1-s2.0-S2214914724001892-main.pdf\" target=\"_blank\" rel=\"noopener\"><img loading=\"lazy\" class=\"aligncenter wp-image-5168\" src=\"https:\/\/www.fie.undef.edu.ar\/ceptm\/wp-content\/uploads\/2020\/02\/icono-PDF-1-243x300.png\" alt=\"Descargar archivo pdf\" width=\"75\" height=\"93\" srcset=\"https:\/\/www.fie.undef.edu.ar\/ceptm\/wp-content\/uploads\/2020\/02\/icono-PDF-1-243x300.png 243w, https:\/\/www.fie.undef.edu.ar\/ceptm\/wp-content\/uploads\/2020\/02\/icono-PDF-1.png 310w\" sizes=\"(max-width: 75px) 100vw, 75px\" \/><\/a><strong>Fuente: <\/strong><a href=\"https:\/\/www.sciencedirect.com\/science\/article\/pii\/S2214914724001892?via%3Dihub\" target=\"_blank\" rel=\"noopener\"><em>https:\/\/www.sciencedirect.com<\/em><\/a><\/p>\n<\/div>\n","protected":false},"excerpt":{"rendered":"<p>En este trabajo, se presenta un estudio comparativo de las propiedades bal\u00edsticas de un compuesto intermet\u00e1lico de aluminuro de hierro F3AC, frente un acero especial&hellip; <\/p>\n","protected":false},"author":1,"featured_media":15326,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":[],"categories":[18,24],"tags":[],"_links":{"self":[{"href":"https:\/\/www.fie.undef.edu.ar\/ceptm\/index.php?rest_route=\/wp\/v2\/posts\/15324"}],"collection":[{"href":"https:\/\/www.fie.undef.edu.ar\/ceptm\/index.php?rest_route=\/wp\/v2\/posts"}],"about":[{"href":"https:\/\/www.fie.undef.edu.ar\/ceptm\/index.php?rest_route=\/wp\/v2\/types\/post"}],"author":[{"embeddable":true,"href":"https:\/\/www.fie.undef.edu.ar\/ceptm\/index.php?rest_route=\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/www.fie.undef.edu.ar\/ceptm\/index.php?rest_route=%2Fwp%2Fv2%2Fcomments&post=15324"}],"version-history":[{"count":1,"href":"https:\/\/www.fie.undef.edu.ar\/ceptm\/index.php?rest_route=\/wp\/v2\/posts\/15324\/revisions"}],"predecessor-version":[{"id":15327,"href":"https:\/\/www.fie.undef.edu.ar\/ceptm\/index.php?rest_route=\/wp\/v2\/posts\/15324\/revisions\/15327"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.fie.undef.edu.ar\/ceptm\/index.php?rest_route=\/wp\/v2\/media\/15326"}],"wp:attachment":[{"href":"https:\/\/www.fie.undef.edu.ar\/ceptm\/index.php?rest_route=%2Fwp%2Fv2%2Fmedia&parent=15324"}],"wp:term":[{"taxonomy":"category","embeddable":true,"href":"https:\/\/www.fie.undef.edu.ar\/ceptm\/index.php?rest_route=%2Fwp%2Fv2%2Fcategories&post=15324"},{"taxonomy":"post_tag","embeddable":true,"href":"https:\/\/www.fie.undef.edu.ar\/ceptm\/index.php?rest_route=%2Fwp%2Fv2%2Ftags&post=15324"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
