(By comparison, AA 6061 has a tensile strength of 186 MPa in welded joints.) According to the study, post-welding heat treatments could further increase the strength of AA 7075 joints up to 551 MPa, which is comparable to steel.<\/span><\/span><\/span><\/span><\/p>\n<p style=\"margin-bottom:.0001pt\">&nbsp;<\/p>\n<p style=\"margin:0in; margin-bottom:.0001pt\"><span style=\"line-height:normal\"><span style=\"tab-stops:76.5pt\"><span style=\"font-size:12.0pt\"><span style=\"font-family:&quot;Calibri&quot;,sans-serif\">&#8220;The new technique is just a simple twist, but it could allow widespread use of this high-strength aluminum alloy in mass-produced products such as cars or bicycles, where parts are often assembled together,&#8221; said Xiaochun Li, UCLA&#8217;s Raytheon Professor of Manufacturing and the study&#8217;s principal investigator. &#8220;Companies could use the same processes and equipment they already have to incorporate this super-strong aluminum alloy into their manufacturing processes, and their products could be lighter and more energy efficient, while still retaining their strength.&#8221;<\/span><\/span><\/span><\/span><\/p>\n<p style=\"margin-bottom:.0001pt\">&nbsp;<\/p>\n<p style=\"margin:0in; margin-bottom:.0001pt\"><span style=\"line-height:normal\"><span style=\"tab-stops:76.5pt\"><span style=\"font-size:12.0pt\"><span style=\"font-family:&quot;Calibri&quot;,sans-serif\">The researchers already are working with a bicycle manufacturer on prototype bike frames that would use the alloy; and the new study suggests that nanoparticle-infused filler wires could also make it easier to join other hard-to-weld metals and metal alloys.<span style=\"font-size:12px;\">&nbsp;<\/span><\/span><\/span><\/span><\/span><\/p>\n<p style=\"margin:0in; margin-bottom:.0001pt\">&nbsp;<\/p>\n<p style=\"margin:0in; margin-bottom:.0001pt\"><span style=\"line-height:normal\"><span style=\"tab-stops:76.5pt\"><span style=\"font-size:12.0pt\"><span style=\"font-size:14px;\"><span style=\"color:#222222\"><span style=\"letter-spacing:.15pt\">\u201cNanoparticle-enabled phase control for arc welding of unweldable aluminum alloy 7075,\u201d was published in the January 9 issue of <i>Nature Communications.<\/i><\/span><\/span><\/span><\/span><\/span><\/span><\/p>\n<h1 style=\"margin-top:0in\"><span style=\"background:white\"><span style=\"line-height:normal\"><span style=\"font-size:12.0pt\"><span style=\"font-family:&quot;Calibri&quot;,sans-serif\"><a href=\"https:\/\/samueli.ucla.edu\/nanotechnology-enables-engineers-to-weld-previously-un-weldable-aluminum-alloy\">https:\/\/samueli.ucla.edu\/nanotechnology-enables-engineers-to-weld-previously-un-weldable-aluminum-alloy<\/a>&nbsp;<\/span><\/span><\/span><\/span><\/h1>\n","protected":false},"excerpt":{"rendered":"<p>Engineers at the UCLA Samueli School of Engineering announce that they have developed a way to weld aluminum alloy AA 7075 by infusing titanium carbide nanoparticles into welding wires, which results in welded joints with a tensile strength up to 392 MPa.<\/p>\n","protected":false},"author":63082,"featured_media":0,"comment_status":"closed","ping_status":"closed","sticky":false,"template":"","format":"standard","meta":{"_acf_changed":false,"footnotes":""},"categories":[444,446,461,456,440,441,1],"tags":[],"class_list":["post-8450","post","type-post","status-publish","format-standard","hentry","category-aerospace-and-defense","category-automobiles-and-ground-transportation","category-consumer-products","category-nanotechnology","category-news","category-news-articles","category-uncategorized"],"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v27.9 -
