This ribbon is converted into flakes and finally into an extrusion product, after which a special heat treatment may be applied. The name &#8220;rapid solidification process&#8221; stems from the sudden temperature drop that takes place at a rate of more than 1,000,000\u02daC per second as the aluminum comes in contact with the wheel.<\/p>\n<p>Thanks to the rapid quenching of the meltspinning process, grain sizes are very small (~2 microns). Intermetallic phases and non-soluble constituents are refined and homogeneously distributed into the matrix, and are characterized by a more favorable morphology. To a large extent, these factors contribute to the improved ductility of the alloy.<\/p>\n<p>The natural maximum solubility imposes major limits to the content of alloying elements in conventional DC casting. However, the meltspinning process&nbsp;generates ultrafast cooling rates. This creates great flexibility, thereby allowing the production of new and exotic alloy compositions such as AlSi40%X or AlFe15%X. Thus, meltspinning is capable of providing custom solutions for applications that require special requirements.<\/p>\n<p>Transmet Corp., Columbus, Ohio, a manufacturer and supplier of rapidly solidified metals, will be the sole U.S. contact for sales and service for RSP Technology billet products.<\/p>\n<p><a href=\"https:\/\/nam10.safelinks.protection.outlook.com\/?url=http%3A%2F%2Fwww.transmet.com%2F&amp;data=02%7C01%7Cmargaret.hunt%40asminternational.org%7Cad19136d885d46dcebb008d85a5a7a70%7C9ca5347b2c51447995329f98f21e059c%7C0%7C1%7C637358691944320566&amp;sdata=6ju3lZn2nuwENryPwbi4Fqh14BWgysUgLitJVQiXzLs%3D&amp;reserved=0\">www.transmet.com<\/a><\/p>\n<p><a href=\"http:\/\/www.rsp-technology.com\">http:\/\/www.rsp-technology.com<\/a>&nbsp;<\/p>\n","protected":false},"excerpt":{"rendered":"<p>RSP Technology, The Netherlands, announces that it has developed a superfast aluminum melt-spinning process that produces billets with an almost nano-grained crystalline structure that can be machined like conventional aluminum, but resulting parts will be as strong as titanium.<\/p>\n","protected":false},"author":63103,"featured_media":0,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"_acf_changed":false,"footnotes":""},"categories":[456,440,441,1],"tags":[],"class_list":["post-9950","post","type-post","status-publish","format-standard","hentry","category-nanotechnology","category-news","category-news-articles","category-uncategorized"],"yoast_head":"<!-- This site is optimized with the Yoast SEO plugin v27.9 -
