SBIR-STTR Award

The project will develop a new processing technology of equal-channel angular extrusion (ECAE) providing semi-continuous multipass ECAE without necessity for billet cleaning, reshaping and preheating between passes. This approach turns ECAE into an effective operation that can be applied at large metallurgical scale and to massive production. Followed rolling, low-cost bulk products such as plates and sheets with ultra-fine grained and nano structures having superior properties are fabricated for different applications. Particular applications are high strength aluminum alloy armor plates and rolled products for precision forging, panel forming, superplastic forming and deep drawing in defence, aerospace, automotive and others industries.

Development of Equal Channel Angular Extrusion (ECAE) protoytpe tooling and processing tehnology for large metallurgical scale and acceptable for typical production floor and ordinary manufacturing environment. Processing of large billets, 250-350 kg, of ultra-fined/nano grain structure suitaable for rolling into comercially sized plate and sheet product. This product is expected to find numerous applications. Further, it is expected that the technology can yield significant "green" benefits by enabling the use of more highly recycled materials in the manufacture of commercial plate and sheet products that can compete with existing product using virgin or lesser recyled material.
